Laser Particle Sensor Module
PM2105L
Applications
▪ Air purifier ▪ Air quality monitor ▪ Air conditioner ▪ Ventilation system ▪ Consumer electronic products ▪ Environmental monitoring
Description
PM2105L is a laser particle sensor module for indoor use based on laser scattering technology. This sensor can measure particle concentration size between 0.3μm~10μm exactly and output particle mass concentration PM1.0, PM2.5, PM10 in μg/m³ directly via mathematical algorithm and scientific calibration.
Features
▪ The smal est size of available measurement: 0.3μm ▪ Real-time output PM1.0, PM2.5, PM10 in μg/m3 available ▪ High accuracy, high sensitive and quick response (≤8s) ▪ Signal output optional: UART, I²C, PWM ▪ RoHS and Reach compliant ▪ Air inlet and outlet on different side
Working Principle
Sampling by the internal pressure which occurs by fan, when sampling particles pass through light beam (laser), there wil be light scattering phenomenon. Scattered light wil be converted into electrical signal (pulse) via photoelectric transformer. The bigger particles wil obtain stronger pulse signal (peak value). Through peak value and pulse value quantity concentration of particles in each size can be calculated. Thus, real-time measured data is obtained through measuring quantity and strength of scattered light. www.en.gassensor.com.cn 2/19 Document Outline Description Features Working Principle Specifications Dimensions and Connector 1.Dimensions (Unit mm, tolerance ±0.2 mm) Typical Application Circuit Case 1.UART3.3V Application Product Installation User Attention UART Communication Protocol 1.
