{"product_id":"mpl115a2-i2c-barometric-pressuretemperature-sensor","title":"MPL115A2 - I2C Barometric Pressure\/Temperature Sensor","description":"\u003cp\u003eThis pressure sensor from Freescale is a great low-cost sensing solution for measuring barometric pressure. At 1.5 hPa resolution, it's not as precise as our favorite pressure sensor, the BMx280 series, which has up to 0.03 hPa resolution so we don't suggest it as a precision altimeter. However, it's great for basic barometric pressure sensing. The sensor is soldered onto a PCB with 10K pull-up resistors on the I2C pins.\u003cbr\u003e\u003cbr\u003eThis chip is good for use with power and logic voltages ranging from 2.4V to 5.5V so you can use it with your 3V or 5V microcontroller. There's a basic temperature sensor inside but there's no specifications in the datasheet so we're not sure how accurate it is.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThis chip looks and sounds a whole lot like the MPL3115A2 but this is the less precise version, best for barometric sensing only\u003c\/strong\u003e\u003cbr\u003e\u003cbr\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 our MPL115A2 Arduino library and example code for temperature, pressure and basic altitude calculation. 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\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003ePCB weight: 0.61g\u003c\/li\u003e\n\u003cli\u003eVin: 2.4 to 5.5 VDC\u003c\/li\u003e\n\u003cli\u003eLogic: 3 to 5V compliant\u003c\/li\u003e\n\u003cli\u003ePressure sensing range: 500-1150 hPa (up to 10Km altitude)\u003c\/li\u003e\n\u003cli\u003e1.5 hPa \/ 50 m altitude resolution\u003c\/li\u003e\n\u003cli\u003eThis board\/chip uses I2C 7-bit address 0x60\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMPL115A2 Datasheet\u003c\/p\u003e\n\u003cp\u003eFritzing object in Adafruit Fritzing library\u003c\/p\u003e\n\u003cp\u003eEagleCAD PCB files on GitHub\u003c\/p\u003e\n\u003cp\u003eUsing the sensor is easy.
