    -Titulo Original : Adafruit Magnetic contact switch (door sensor) [ADA375]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 375 // Stock Type: Sensors >> Proximity // In Stock & Ready to Ship // This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. When the magnet is less than 13mm (0.5) away, the reed switch closes. They're often used to detect when a door or drawer is open, which is why they have mounting tabs and screws. You can also pick up some double-sided foam tape from a hardware store to mount these, that works well without needing screws...

  • Adafruit 3966 BMP388 - Precision Barometric Pressure And Alt
    Precio:  $66,549.00

    Adafruit 3966 BMP388 - Precision Barometric Pressure And Alt

    -Titulo Original : Adafruit BMP388 - Precision Barometric Pressure And Altimeter (3966)-Fabricante : Adafruit-Descripcion Original: Product Dimensions: 21.6mm x 16.6mm x 3.0mm / 0.9" x 0.7" x 0.1" // Product Weight: 1.2g / 0.0oz // Bosch has been a leader in barometric pressure sensors, from the BMP085. BMP180, and BMP280... now we've got the next generation, the Adafruit BMP388 Precision Barometric Pressure sensor. As you would expect, this sensor is similar to its earlier versions but even better. The BMP388 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations. The BMP3xx is the next-generation of sensors from Bosch, and is the upgrade to the BMP280 - with a low altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI. This sensor has a relative accuracy of 8 Pascals, which translates to about ± 0.5 meter of altitude (compare to the BMP280's 12 Pascal/ ±1 meter). The datasheet sort of implies they intend this sensor to be used for drones and quadcopters, to keep altitude stable, but you could also use this for wearables or any project that wants to track height-above-sea-level. Note that for absolute height you'll still need to enter in the barometric pressure at sea level, if the weather changes, but that's true of every altimeter sensor that uses pressure. You can also measure temperature with ±0.5°C accuracy. Nice sensor right? So we made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a PCB and comes with a 3.3V regulator and level shifting so you can use it with a 3V or 5V logic microcontroller without worry. Check out the Arduino library to get data out in under 10 minutes...

  • Adafruit 4258 LPS35HW Water Resistant Pressure Sensor
    Precio:  $78,479.00

    Adafruit 4258 LPS35HW Water Resistant Pressure Sensor

    -Titulo Original : Adafruit 4258 LPS35HW Water Resistant Pressure Sensor-Fabricante : Adafruit-Descripcion Original: water resistant barometric pressure and temperature sensor that is also safe to use in wet environments // should work well for normal wet situations like weather stations or high humidity // 260 to 1260 hPa absolute pressure range // 24-bit pressure data output -- ODR from 1 Hz to 75 H // 16-bit temperature data output -- SPI and I²C interfaces // Sometimes you need to sense pressure in a damp environment. And sometimes you need to know the relative changes in pressure as well as the absolute pressure. For the times you need to do both (or either), the LPS35HW is the pressure sensor for you. Combining protection from water intrusion with support for high precision relative and absolute measurements, this sensor will do what you need. With drivers for CircuitPython, Arduino, and Raspberry Pi, and support for I2C or SPI (Arduino only SPI support, for now) you'll be measuring pressure in moist situations in no time. The ST LPS35HW is a water resistant barometric pressure and temperature sensor that is also safe to use in wet environments. The sensing element is nestled safely in a ceramic package and is encased in a waterproof gel that prevents water that gets into the sensor from interfering with readings. It does not carry any ratings for resistance to moisture so you probably don't want to take it to the bottom of the Mariana Trench, but it should work well for normal wet situations like weather stations or high humidity. Along with not being afraid of getting wet, the LPS35HW has a 24bit pressure data and 16 bit temperature data, allowing it to deliver pressure readings with +/- 0.1% hPa accuracy. It can measure from 260 to 1260 hPa and is able to withstand pressure up to 20 times its measurement range. To help you take measurements to your requirements, the LPS35HW also offers an adjustable data rate, as well as a low pass filter to remove noise from the signal. Finally, the onboard temperature compensation makes sure that your readings are always good and won't vary as the temperature changes. We placed this sensor on a breakout board with a 3.3V regulator and level shifting circuitry so it can be used by 3V or 5V power/logic devices. A small piece of header is also included, so you can solder it in for use with a breadboard...

    Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3

    -Titulo Original : Adafruit L3GD20H Triple-Axis Gyro Breakout Board - L3GD20/L3G4200 Upgrade - L3GD20H [ADA1032]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1032 // Stock Type: Sensors >> Motion // In Stock & Ready to Ship // A gyroscope is a type of sensor that can sense twisting and turning motions. Often paired with an accelerometer, you can use these to do 3D motion capture and inertial measurement (that is - you can tell how an object is moving!) As these sensors become more popular and easier to manufacture, the prices for them have dropped to the point where you can easily afford a triple-axis gyro! Only a decade ago, this space-tech sensor would have been hundreds of dollars. This breakout board is based around the latest gyro technology, the L3GD20H from STMicro . It's the upgrade to the L3G4200 ( see this app note on what to look for if upgrading an existing design to the L3GD20 ) with three full axes of sensing. The chip can be set to ±250, ±500, or ±2000 degree-per-second scale for a large range of sensitivity. There's also built in high and low pass sensing to make data processing easier. The chip supports both I2C and SPI so you can interface with any microcontroller easily. Since this chip is a 3.3V max device, but many of our customers want to use it with an Arduino, we soldered it to a breakout board with level shifting circuitry so you can use the I2C or SPI interface safely using a 5V interface device. We also place a 3.3V regulator on there so you can power it from 5V. Since we expect people will want to attach it firmly to their project, the PCB comes with four 2.1mm mounting holes. Use #2-56 imperial or M2 screws screws. Getting started is easy - simply connect SDA to your Arduino I2C data pin (On the UNO this is A4), SCL to I2C clock (Uno: A5), GND to ground, and Vin to 3 or 5VDC. Then install and run our easy to use Arduino library, which will print out the XYZ sensor data to the serial terminal. Our library also supports SPI on any 4 digital I/O pins, see the example for wiring...

    -Titulo Original : Adafruit Pro Trinket LiIon/LiPoly Backpack Add-On-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2124 // Stock Type: Power >> LiIon & LiPoly >> Accessories // In Stock & Ready to Ship // If you have a Pro Trinket you probably know it's the perfect little size for a portable project. This LiPoly backpack makes it really easy to do! Instead of wiring 2 or 3 boards together to make a charging system, this little PCB sits on top of the Pro Trinket and allows a LiPoly/LiIon battery to plug in. When the Pro Trinket USB port is powered, the battery is recharged automatically. Unplug the USB port and the Pro Trinket will switch over to the rechargeable battery.Ideally, this backpack is for use with the 3.3V Pro Trinket, so that the battery voltage (3.7V-4.2V) will get regulated down to 3.3V on the Pro Trinket board. However, many times, you can run a 5V Pro Trinket + accessories off of the ~4V from the LiPoly battery with no problem. (Technically its overclocking but we've never seen that affect the Pro Trinket itself, AVRs are happy to overclock without complaint).Solder the backpack on with the extra long header so that it can still plug into a breadboard, or clip the long header leads short afterwards for a slim package. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy.If you want to add an On/Off switch, we also made that really easy. The two 0.1 holes with a box around them are the battery output line. Carefully cut the trace between them with a hobby knife and replace with two wires from a switch like this slide switch , or this pushbutton one , for example. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the bottom, for when you'l...

    -Titulo Original : Adafruit (PID 3229 Radio FeatherWing - RFM69HCW 900MHz-Fabricante : Adafruit-Descripcion Original: SX1231 based module with SPI interface // Packet radio with ready-to-go Arduino libraries // Uses the license-free ISM bands // +13 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software) // 50mA (+13 dBm) to 150mA (+20dBm) current draw for transmissions // Add short-hop wireless to your Feather with these Radio Featherwings. These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x's). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device. These radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with, and are well known and understood. The LoRa radios are exciting, longer-range and more powerful but also more expensive. RFM69 @ 433 MHz - basic packetized FSK/GFSK/MSK/GMSK/OOK radio at 433 MHz for use in Europe ITU 1 license-free ISM, or for amateur use with restrictions (check your local amateur regulations!) RFM69 @ 900 MHz - basic packetized FSK/GFSK/MSK/GMSK/OOK radio at 868 or 915 MHz for use in Americas ITU 2 license-free ISM, or for amateur use with restrictions (check your amateur regulations!) RFM98 @ 433 MHz - LoRa capable radio at 433 MHz for use in Europe ITU 1 license-free ISM, or for amateur use with restrictions (check your local amateur regulations!) RFM95 @ 900 MHz - LoRa capable radio at 868 or 915 MHz for use in Americas ITU 2 license-free ISM, or for amateur use with restrictions (check your local amateur regulations!) This is the RFM69 @ 900 MHz version, it can be used for 868 MHz or 915 MHz (the radios use software configured frequency) These are +20dBm FSK packet radios that have a lot of nice extras in them such as encryption and auto-retransmit. They can go at least 500 meters line of sight using simple wire antennas, probably up to 5Km with directional antennas and settings tweaking...

Enter Ada-friend Mike Doell to the rescue! This minimal but elegant acrylic case will turn your board into an electronic snowflake. The enclosure is designed to snap together securely with no tools required. You can still press all the buttons and slide the switch thanks to a clever plastic widget fitted inside. The case winds around all the touch pads so you can still touch them or attach alligator clips. On the back, we have two slots that can be used to pass through ribbon or webbing up to 1 /2.5mm wide There is also a slim 1/4-20 nut that is embedded in the center back. This is compatible with any camera mounting accessory, so if you need a solid attachment, you can use any camera positioning tool or tripod. Since it's crystal clear, you can see all the NeoPixels shining in glorious color. The light sensor also works just fine and the case will not block IR messages going in or out. Even though there are no microphone or speaker holes, audio passes through the case via various small openings - we tested it and the difference is barely noticeable. This enclosure is only compatible with the Circuit Playground Express! This case will protect your Circuit Playground Express from every day usage, but it is not waterproof or weatherproof. This product comes as 2 molded plastic halves with the buttons in place. No boards, cables, or accessories are included...

    Adafruit Feather M4 Express - Featuring ATSAMD51 - ATSAMD51

    -Titulo Original : Adafruit Feather M4 Express - Featuring ATSAMD51 - ATSAMD51 Cortex M4-Fabricante : ADAFRUIT-Descripcion Original: 512KB Flash and 192KB RAM // ATSAMD51J19 // 120MHz Cortex M4 // It's what you've been waiting for, the Feather M4 Express featuring ATSAMD51. This Feather is fast like a swift, smart like an owl, strong like a ox-bird (it's half ox, half bird, OK?) This feather is powered by our new favorite chip, the ATSAMD51J19 - with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset. And best of all, it's a Feather - so you know it will work with all our FeatherWings! What a great way to quickly get up and running. The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE - and it's bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. When you're done, unplug the Feather and your code will go with you. The Feather M4 Express uses the extra space left over to add a Mini NeoPixel, 2 MB SPI Flash storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB...
