Plantower® G5 PMS5003 PM2.5 Sensor Accurately Smog Serial Port High Precision

Feature This sensor uses the principle of light scattering That is the 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 10MicroParticle count efficiency50 0 3 micro 98 0 5 micro Particle mass concentration effective range PM2 5 standard value 0 500Microgram cubic meterParticle mass concentration resolution1Microgram cubic meterParticle mass concentration consistency±10 100 500 μg m3 PM2 5 standard value ±10 μg m3 0 100 μg 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 60°COperating humidity range0 99 Storage temperature range 40 80°CMean time between failures 3YBiggest size50 x 38 x 21mmPin Description 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 incl
