Bosch BMV080-Based Ultra-Mini Particulate Matter Sensor Module with I2C and Qwiic Interface for Air Quality Monitoring
The 7Semi BMV080 sensor module is a compact air quality sensing board built around the Bosch Sensortec BMV080 ultra-mini particulate matter sensor. Designed for space-constrained and power-sensitive applications, the board measures airborne particle concentrations across PM1.0, PM2.5, and PM10 size ranges, delivering real-time air quality data over an I2C interface. At just 31 x 11 x 4.7 mm, the module fits seamlessly into wearables, IoT devices, and smart home systems where a full-sized sensor would not be practical. The laser-scattering measurement principle enables accurate, reliable dust-particle detection without the need for active airflow management, as the BMV080 works with naturally occurring ambient airflow around the sensor.
The board includes Qwiic-compatible JST connectors, allowing plug-and-play integration with popular microcontroller ecosystems without any soldering. Operating at 3.3V and across a wide temperature range of -40 to +60 degrees C, the module is well-suited for both indoor and outdoor deployments. With a PM concentration measurement range of 0 to 1000 ug/m3 and an accuracy of plus or minus 10 ug/m3 within the 0 to 100 ug/m3 range, it meets the requirements of air quality monitoring, environmental sensing, and health-conscious smart-device applications that demand both precision and miniaturisation.
