GY-68 BMP180 Digital Atmospheric Pressure Module

The BMP180 is a precision barometric pressure, temperature and altitude sensor from manufactured by Bosch. It is fully compatible with BMP085 in terms of firmware/software/interfacing. BMP180 can easily be configured to work with Arduino, ARM or PIC over I2C.

Specification:

• 3-5V Logic and Power
• 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.
