Bosch BME680 Digital Temperature Humidity Pressure VOC Gas Sensor Module CJMCU-680 Development Board - I2C/SPI Interface
The CJMCU-680 development board integrates the Bosch BME680 digital environmental sensor, providing precise temperature, humidity, barometric pressure, and indoor air quality (VOC) sensing via I2C or SPI interfaces for Arduino, Raspberry Pi, ESP32, and other microcontroller platforms.
Features
- Bosch BME680 sensor measures temperature (±1.0°C), humidity (±3%), pressure (±1 hPa), and VOC gas index.
- Dual I2C and SPI digital interfaces for flexible system integration.
- High-precision barometric pressure enables altitude estimation (±1 meter).
- Low-power operation suitable for battery-powered environmental monitoring nodes.
- Breakout board with pre-soldered 6-pin header for easy breadboard prototyping.

The CJMCU-680 module is a breakout board for the Bosch BME680, a 4-in-1 environmental MEMS sensor. It combines a high-linearity pressure sensor, a dedicated humidity sensing layer, a temperature sensor, and a metal-oxide (MOX) gas sensor sensitive to volatile organic compounds (VOCs) for indoor air quality assessment. The sensor communicates via a fully digital interface, supporting both I2C and SPI protocols for direct connection to microcontrollers and single-board computers.
This module provides a stable 3.3V regulated supply to the BME680 from a 5V input, ensuring reliable operation. The board includes a 6-pin header (VCC, GND, SDA/SDI, SCL/SCK, SDO, CS) for flexible wiring. The BME680’s integrated signal conditioning and 24-bit ADC deliver calibrated digital outputs, minimizing the need for external analog circuitry and simplifying firmware development for environmental data logging, weather stations, and smart home automation.
