This Crowtail- BME280 Atmospheric Sensor is the easy way to measure barometric pressure, humidity, and temperature readings all without taking up too much space. Basically, you can find out anything you need to know about atmospheric conditions from this board.

The Crowtaill- BME280 Atmospheric Sensor has been design to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring. The Crowtail- BME280 Atmospheric Sensor measures atmospheric pressure from 30kPa to 110kPa as well as relative humidity and temperature.

The Board provides a 5V tolerant I2C interface (with pull-up resistors to 3.3V), takes measurements at less than 1mA and idles less than 5uA.
