BME680 MODULE

The BME680 (CJMCU-680) is a 4-in-1 environmental sensor measuring temperature, humidity, barometric pressure, and VOC gas concentration. Supports both I2C and SPI interfaces. High-linearity, high-accuracy sensing suitable for air quality monitoring, weather stations, and IoT nodes. Header soldering required.

Note: The gas sensor detects VOC concentration via resistance changes and requires calibration for precision output. Not suitable for safety or medical applications.
