PandaByte Particulate Matter (PM) Sensor Module is a compact and reliable solution for real-time air quality monitoring. Powered by the Winsen ZH03B PM sensor, it accurately measures PM1.0, PM2.5, and PM10 concentrations and outputs data via UART and PWM interfaces. Designed for rapid prototyping, the module features both standard 2.54 mm headers for Dupont cables and a Grove connector, making it easy to integrate with microcontrollers and development boards for environmental sensing projects.
