Environment Sensor Module

BMP180 combines barometric pressure, temperature, and altitude. The I2C allows easy interface with any microcontroller. The onboard 3.3V LDO regulator makes this board fully 5V supply-compatible. BMP-180 can measure pressure range from 300 to 1100hPa (+9000m to -500m relating to sea level) with an accuracy down to 0.02hPa (0.17m) in advance resolution mode. BMP-180 uses piezo-resistive technology for high accuracy, linearity, EMC robustness, and stability for a longer period.

The BMP280 sensor is a high-precision module capable of detecting atmospheric temperature, pressure, and humidity. It supports both the SPI and I2C interfaces and comes pre-calibrated, eliminating the need for additional calibration before use. This is an inexpensive sensor that measures temperature and barometric pressure, but because pressure varies with altitude, we can also use it as an altimeter with an accuracy of about one meter.
