BMP085 Barometric Pressure Sensor Module

BMP085 Barometric Pressure Sensor Module

This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a filter capacitor and two pull-up resistors on the I2C pins.

Using the sensor is easy. For example, if you’re using an Arduino, simply connect the VCC pin to the 3.3V voltage pin, GND to ground, SCL to I2C Clock (Analog 5) and SDA to I2C Data (Analog 4). Then download our BMP085 Arduino library and example code for temperature, pressure and altitude calculation. Install the library, and load the example sketch. Immediately you’ll have precision temperature, pressure and altitude data.
