{"product_id":"adafruit-mpl3115a2-i2c-barometric-pressure-altitude-temperature-sensor","title":"MPL3115A2 - I2C Barometric Pressure\/Altitude\/Temperature Sensor","description":"\u003cp\u003eThis pressure sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude.\u003c\/p\u003e\n\u003cp\u003eThe MPL3115A2 has a typical 1.5 Pascal resolution, which can resolve altitude at 0.3 meters (compare to the BMP180 which can do 0.17m). \u003ca href=\"\/en-eu\/products\/adafruit-bmp280-i2c-or-spi-barometric-pressure-altitude-sensor\" target=\"_blank\"\u003eIt has some upsides compared to the BMP280\u003c\/a\u003e, such as interrupt outputs for ultra-low power usage, and its also a heck of a lot easier to read altitude with a built in altimeter calculation - no calibration reading and calculating required. As a bonus, there's even a fairly good temperature sensor with ±1°C typical accuracy (±3°C max).\u003c\/p\u003e\n\u003cp\u003eThis chip likes to be used with 2-3.6V power and logic voltages, so Adafruit placed it on a breakout with a 3V regulator and logic level shifting. Its easy to use with any Arduino or microcontroller that has i2c capability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis chip looks and sounds a whole lot like the \u003ca href=\"\/en-eu\/products\/adafruit-i2c-barometric-pressure-temperature-sensor\" target=\"_blank\"\u003eMPL115A2\u003c\/a\u003e but this is the precision version, which can act as an altitude-sensor as well as barometer\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUsing the sensor is easy. For example, if you're using an Arduino, simply connect the VDD pin to the 5V voltage pin, GND to ground, SCL to I2C Clock (Analog 5 on an UNO) and SDA to I2C Data (Analog 4 on an UNO). Then download the \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_MPL3115A2_Library\" target=\"_blank\"\u003eMPL3115A2 Arduino library and example code for temperature, pressure and basic altitude calculation.\u003c\/a\u003e Install the library, and load the example sketch. Immediately you'll have the temperature, pressure and altitude data printed in the serial console.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 18mm x 19mm x 2mm \/ .7\" x .8\" x .1\"\u003c\/li\u003e\n\u003cli\u003eWeight: 1.2g\u003c\/li\u003e\n\u003cli\u003eVin: 3 to 5.5 VDC\u003c\/li\u003e\n\u003cli\u003eLogic: 3 to 5V compliant\u003c\/li\u003e\n\u003cli\u003ePressure sensing range: 50-110 kPa (up to 10Km altitude)\u003c\/li\u003e\n\u003cli\u003e1.5 Pa \/ 0.3 m altitude resolution\u003c\/li\u003e\n\u003cli\u003eThis board\/chip uses I2C 7-bit address 0x60\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/datasheets\/1893_datasheet.pdf\" target=\"_blank\"\u003eMPL3115A2 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit-MPL3115A2-PCB\" target=\"_blank\"\u003eEagleCAD PCB files on GitHub\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Fritzing-Library\" target=\"_blank\"\u003eFritzing object in Adafruit Fritzing library\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":782394401,"sku":"ADA1893","price":9.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/1893-02.jpg?v=1576072736","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/adafruit-mpl3115a2-i2c-barometric-pressure-altitude-temperature-sensor","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
