7Semi BME690 Digital Sensor Probe - Metal (Temperature, Humidity, Pressure, Gas | I2C)

The 7Semi BME690 Digital Sensor Probe is a compact 4-in-1 environmental sensing solution designed to measure temperature, relative humidity, barometric pressure, and gas/air-quality parameters. Built around the Bosch Sensortec BME690, it combines multiple environmental measurements in a single probe for indoor air-quality monitoring, HVAC systems, smart buildings, IoT devices, environmental monitoring, and industrial applications.

The probe communicates through a digital I²C interface and provides temperature, humidity, pressure, and gas-resistance measurements. When used with compatible Bosch BSEC software, the gas-sensing data can also be processed to provide air-quality outputs such as IAQ, bVOC-equivalent, and CO₂-equivalent values.

Its rugged metal probe construction provides mechanical protection to the internal sensing element while allowing exposure to the surrounding environment for effective measurement. The remote probe design makes it suitable for applications where the sensing point needs to be positioned away from the host electronics, providing a practical solution for long-term environmental and air-quality monitoring.
