BMP180 Digital Barometric Sensor Module – Model GY-68

Description 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 3.3V regulator, and pull-up resistors on the I2C pins. The BMP180 is the next-generation of sensors from Bosch, and replaces the BMP085. The good news is that it is completely identical to the BMP085 in terms of firmware/software/interfacing – you can use any example code/libraries for BMP085 as a drop-in replacement. Technical Specifications Vin: 2.0 to 5VDC Logic: 1.8V / 3.3V compliant Pressure sensing range: 300-1100 hPa (9000m to -500m above sea level) Up to 0.03hPa / 0.25m resolution -40 to 85°C operational range, -2°C temperature accuracy This board/chip uses I2C 7-bit address 0x77.
