The PlanTower PMSA003-A Dust and Air Quality Sensor is a highly accurate laser-based module designed to measure PM1.0, PM2.5, and PM10 concentrations in real time. Using advanced laser light scattering technology, the PMSA003-A can detect particles as small as 0.3 µm, making it suitable for monitoring pollutants like dust, cigarette smoke, and vehicle emissions. Its integrated silent fan ensures stable airflow for consistent and precise readings. With a UART interface (3.3V logic level) and wide operating voltage range (3.3V–5V), this compact sensor is ideal for IoT air quality systems, HVAC integration, smart home devices, and environmental analysis tools.
