Plantower® PMS5003T PM2.5+Temperature and Humidity Two-in-one Sensor Detector

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 Pin 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 includes 1 x PM2 5 Sensor1 x Cable
