BME280 – Pressure, humidity and temperature sensor

Description

Ultra-small module (13.3×10.6×3.5 mm) based on the BME280 pressure, humidity, and temperature sensor. It is fully calibrated, ready to use, and supports the I²C and SPI digital interfaces. The I²C interface supports Standard, Fast, and High Speed modes. Power supply: from 1.8 VDC to 5 VDC, interfaces: I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz), pressure range: from 300 hPa to 1100 hPa, temperature range: from -40°C to +85°C, humidity range: from 0 to 100% RH.

Warning! The module is supplied pre-assembled except for the strip connector.
