What it does Measures airborne particle mass concentration with high sensitivity and delivers numeric output via a serial interface. Integrated fan provides active sampling for consistent airflow and repeatable readings. Why you need it Detect smaller changes in particle concentration: 0.3 µg/m3 resolution lets you spot subtle trends and small improvements or degradations in air quality. Reliable, repeatable readings: designed for stable detection and good unit-to-unit consistency, so long-term monitoring and comparative deployments remain trustworthy. Near real-time control and alerts: data refreshes at 1 Hz, enabling timely responses from control systems, ventilation, or alerting software. Key benefits Easy integration: standard serial output simplifies connection to controllers, single-board computers, PLCs, data loggers, and other monitoring systems without complex analog conditioning. Built-in fan: eliminates the need for external sampling fans or pumps, reducing system complexity and helping ensure consistent sample flow over the sensing element. High performance: 0.3 µg/m3 resolution and stable detection characteristics support precise monitoring and analysis. Fast update rate: 1 Hz data refresh supports near-real-time dashboards, feedback loops, and event-driven automation. Compatibility and installation notes Interfaces over serial communications for straightforward wiring and software integration; compatible with common embedded and PC platforms that accept serial input. Integrated sampling fan reduces external hardware needs. Check your enclosure and mounting for required airflow clearance to maintain performance. Power and serial signal levels should be matched to your host system—consult device documentation for exact pinout and electrical requirements. Practical applications Indoor air quality monitoring: continuous measurement for homes, offices, classrooms, and public buildings where detecting small concentration changes matters for health and comfort. HVAC and filtration control: feed 1 Hz particle data into ventilation control systems to trigger fan speed changes, filter diagnostics, or demand-controlled ventilation. IoT and environmental sensing: combine with data loggers and cloud services for distributed air quality networks, mobile monitoring units, or research deployments that require consistent, high-resolution particle data.
