GY-68 BMP180 BMP 180 I2C Digital Barometric Atmospheric Pressure/Altitude/Temperature Sensor Module Arduino ESP32

This precision sensor 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, I2C level shifter and pull-up resistors on the I2C pins.

The BMP180 is the BMP085’s successor and brings to the table more accuracy, better energy consumption and smaller form size. There are plenty of example tutorials and guides for the BMP180; help by the fact it’s a drop-in replacement for the BMP085.

Features:

- Size: approx. 3.6mmx 3.8x 0.93mm
- Drop-in replacement for BMP085
- Its performance is remarkable, the absolute minimum accuracy can reach 0.03 hPa
- Power consumption is extremely low, only 3 mA
- Pinouts are clearly marked on reverse side of board
