Feature:This sensor uses the principle of laser light scattering. That is, the laser illuminates the suspended particles in the air to generate scattering, and at the same time, the scattered light is collected at a certain angle to obtain a curve of the scattered light intensity with time. Furthermore, the microprocessor uses an algorithm based on the MIE theory to obtain the equivalent particle size of the particles and the number of particles of different particle sizes per unit volume.ParameterIndexUnitParticle measurement range0.3~1.0, 1.0~2.5, 2.5~10MicronParticle count efficiency50%@0.3 micron 98%@=0.5 micron Particle mass concentration effective range (PM2.5 standard value)0-500Microgram/cubic meterParticle mass concentration resolution1Microgram/cubic meterParticle mass concentration consistency10%@100-500 g/m3 (PM2.5 standard value)10 g/m3 @0-100 g/cubic Weighing volume0.1LSingle response time1SComprehensive response time=10SDC supply voltageTyp.5.0, Min.4.5, Max.5.5VWorking current=100mAStand-by current=200uAData interface levelL0.8@3.3, H2.7@3.3VWorking temperature -10~+60COperating humidity range0-99% Storage temperature range -40~+80CMean time between failures=3YBiggest size50 x 38 x 21mmPin VCCPower +5VGNDPower supply-SETSet the pin/TTL level @3.3V high or floating to normal operation, low level to sleep stateRXDSerial receiver pin / TTL Level @3.3VTXDSerial transmit pin / TTL level @3.3VRESETModule reset signal / TTL level @3.3V, low resetNC Package
