The 7SEMI Air Quality Sensor Board is a compact, all-in-one solution for environmental monitoring. Powered by an STM32G0B0KET6 microcontroller, the board integrates SEN66 for PM2.5/PM10 particulate matter sensing, BMB585 for barometric pressure, humidity/temperature measurement, and the OPT4048 high-precision ambient light sensor.
This multi-sensor platform supports I²C (Qwiic-compatible) and UART communication, making it ideal for IoT, smart homes, HVAC systems, weather stations, and air-quality monitoring applications.
