• BME688 Breakout Humidity, Pressure, Temperature Air Quality Sensor

BME688 Breakout Humidity, Pressure, Temperature Air Quality Sensor

The Bosch Sensortec BME688 is the successor to the BME680 and offers the same measuring capabilities for humidity, pressure, temperature, and air quality. It has a digital I2C/TWI and SPI interface, which can be operated with a voltage regulator and level converter from 3V to 5V. The main difference between the two sensors is that the BME688 also has two Qwiic connectors on the back.
