The All-in-One Solution for Environmental Monitoring

Tired of wiring multiple, bulky sensors for your smart home or IoT project? The BME680 Digital Environmental Sensor Module (CJMCU-680) combines four highly accurate sensors into one tiny, ultra-efficient board. Whether you are building a custom weather station, an automated greenhouse, or an advanced Indoor Air Quality (IAQ) monitor, this module provides the precise data you need to automate and optimize your environment.

Measure What Matters: Temperature, Humidity, Pressure, and Air Quality

Unlike standard atmospheric sensors, the BME680 integrates a state-of-the-art Metal Oxide (MOX) gas sensor. This allows you to detect Volatile Organic Compounds (VOCs) from paints, cleaning supplies, and everyday household items, giving you a direct reading of your indoor air quality.

Combined with highly stable temperature, humidity, and barometric pressure tracking, you can easily predict weather changes or trigger smart home ventilation systems the moment air quality drops.

Seamless Integration with I2C and SPI

Designed for maximum compatibility, the CJMCU-680 supports both I2C (up to 3.4 MHz) and SPI (up to 10 MHz) communication protocols. It interfaces effortlessly with popular development boards like Arduino, Raspberry Pi, and ESP32.

Please Note: This module operates on a 1.7V to 3.6V logic level. If you are using a 5V microcontroller like an Arduino Uno, a logic level converter is highly recommended to prevent damage.
