The Weather Click Board™ carries BME280 integrated environmental unit from Bosch. It's a sensor that detects humidity, pressure, and temperature, specifically designed for low current consumption and long-term stability. The click is designed to work on a 3.3V power supply. It communicates with the target microcontroller over SPI or I2C interface.

BME280 Features

The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles.

The BME280 IC has high accuracy and reliability for all three sensors. The humidity sensor has a response time of just one second and it's accurate up to ±3% RH. The pressure sensor has sensitivity error of ±0.25% which is equivalent to 1m at 400m height change). The humidity and pressure sensors can operate independently from each other. Finally, the temperature sensor has a high resolution (up to 20 bit, when IIR filter is enabled) and low noise. The chip has three operating modes: sleep, forced, and normal.
