Precision particulate matter sensor module — fast, reliable, and easy to integrate Key benefits Fast, real-time readings: refreshes data at 1 Hz for timely monitoring and control. High sensitivity and resolution: detects fine changes in particulate concentration with 0.3 µg/m3 resolution for detailed measurement and trend analysis. Consistent, stable output: designed for reliable detection with stable signals and good consistency between units. Built-in airflow management: integrated fan provides controlled sampling for repeatable measurements in variable environments. Simple system integration: serial output enables direct connection to microcontrollers, data loggers, PLCs, or other serial-capable controllers without complex interfacing. What it does and how it helps Function: continuously detects airborne particulate matter and provides calibrated digital output at 1 Hz, allowing you to monitor particulate trends, trigger alerts, or drive control actions. How it solves problems: fast updates and fine resolution let you identify short-term spikes and small concentration changes that slower or lower-resolution sensors can miss. Stable, consistent readings reduce false alarms and simplify calibration and maintenance. Compatibility and integration: serial output supports standard UART/RS232/TTL serial connections (use appropriate voltage levels or converters as required), making this sensor suitable for embedded systems, building automation, and portable instruments. Sampling reliability: the built-in fan ensures representative air flow through the sensing chamber, improving repeatability across different installation conditions. Practical applications Indoor air quality monitoring: real-time tracking in homes, offices, classrooms, and cleanrooms to assess filtration performance and occupant exposure. HVAC and building automation: feed 1 Hz particulate data into ventilation controls or filter maintenance systems to optimize air handling and energy use. Environmental and research instruments: incorporate into mobile or stationary monitoring platforms where high resolution and consistent sampling matter.
