Bmp180 - Overview
Pressure & temperature sensor BMP180
The BMP180 Pressure & temperature sensor is an atmospheric sensor that measures two values: temperature and pressure. The digital sensor on the board precisely measures changes in barometric pressure and temperature. It uses the piezoresistive effect to gather information. Since atmospheric pressure varies with altitude, the sensor can also measure altitude. It is simple to use, as it communicates via I2C communication with a hardware-defined address of 0x77 and is designed for seamless Qwiic (formerly easyC) connectivity. Its very low current consumption and voltage make this sensor suitable for many modern devices.
