GY-21P Atmospheric Humidity Temperature Sensor Breakout Barometric Pressure BMP280+SI7021 sensor for Arduino FZ2536
The GY-21P Atmospheric Sensor Breakout is the easy
way to measure barometric pressure, humidity, and temperature readings
all without taking up too much space. Basically, anything you need to
know about atmospheric conditions you can find out from this tiny
breakout. The GY-21P Breakout has been design to be used in
indoor/outdoor navigation, weather forecasting, home automation, and
even personal health and wellness monitoring.
The on-board BMP280+SI7021 sensor measures atmospheric pressure from 30kPa to 110kPa as well as relative humidity and temperature.
