Product description
Environmental sensor with I2C and SPI. The sensor Bosch BME280 measures temperature, air pressure and humidity with high accuracy. Built-in level converters and Qwiic connectors make it quick and easy to connect multiple sensors, and SPI facilitates multi-device projects whilst avoiding address conflicts on the I2C bus.
In addition to power SPI, the I2C pins are also available on the 2.54 mm pitch connector for use with breadboards or prototyping boards. Pin header included (not fitted).
Suitable for education and development, home automation, IoT etc, e.g. building your own weather station. The accurate pressure sensing also makes it useful as an altimeter in e.g. drones.
Compatible with Raspberry Pi and Arduino. Code examples, documentation and libraries are available at Adafruit.
