Description

BME680 Environmental Sensor Module (CJMCU-680) – Temperature, Humidity, Pressure & VOC

This BME680 Environmental Sensor Breakout Board is a high-precision, low-power module that can measure temperature, humidity, barometric pressure, and VOC gas levels with excellent accuracy. It includes both SPI and I²C interfaces, making it easy to integrate with popular microcontrollers (Arduino, ESP8266) and SBCs (Raspberry Pi).

The sensor provides ±3% humidity accuracy, ±1 hPa barometric pressure accuracy, and ±1 °C temperature accuracy, allowing altitude estimation within ±1 m. The VOC sensor works by monitoring changes in internal resistance, making it ideal for air quality monitoring and environmental projects.
Note: It should not be used for any safety, medical, or finished product usage. All gas sensors require calibration for precision output.
