The GY-21P is an interesting module in that it combines a BMP280 sensor and an SI7021 sensor. The on-board BMP280+SI7021 sensor measures atmospheric pressure from 30kPa to 110kPa as well as relative humidity and temperature. Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout. 

Features

  • High quality and durable.
  • Can measure humidity,temperature and barometric pressure.
  • Portable design,easy to carry.
  • Easy to install.
