Key benefits Reliable detection of fine particles: measures particles from 0.3 to 10 um, helping you identify harmful fine dust that is invisible to the eye. precision sensing: designed for consistent, repeatable readings that support airquality decisions and device control. Compact and easy to integrate: small footprint fits into portable devices, monitors, and retrofit systems without adding bulk. Flexible output options: UART, PWM, and IIC outputs allow straightforward connection to microcontrollers, data loggers, and control systems. Main features precision sensor element for consistent particle detection Digital display priority Particle measurement range: 0.3 to 10 um Output methods: UART; PWM; IIC Physical size: 37.8 x 34.8 x 11.8 mm (L x W x H) Performance and compatibility Function: realtime particle concentration measurement across the 0.3–10 um range Compatibility: integrates with systems and controllers that support UART, PWM, or IIC communication protocols Form factor: compact dimensions make mounting and enclosure design simple for both products and upgrades Practical applications Indoor air quality monitors: integrate the sensor into wallmounted or tabletop monitors to display and log fineparticle levels for homes, offices, or classrooms. HVAC and airpurification control: use the sensor output to trigger fans, filters, or purification cycles when particle counts exceed set thresholds. Portable and handheld detectors: the small size and multiple output options enable use in field test equipment, portable inspectors, or maintenance tools. What this product solves Detects fine particulate matter that standard visual checks miss, enabling timely response to poor air quality. Simplifies system integration with multiple, widely supported output interfaces. Minimizes space impact while providing precision measurements suitable for monitoring, control, and data collection. Ordering and integration tips Confirm your host system accepts UART, PWM, or IIC signals before integration. Use the compact mounting area provided by the 37.8 x 34.8 x 11.8 mm footprint to plan enclosures and airflow paths for accurate sampling.
