PMS5003 PM2.5 Sensor Module Air Particle Dust Sensor Module G5 Technology Digital Air Gas Purifier

The sensor adopts the principle of laser-scattering.The scattered light is collected at a certain Angle to obtain the curve of the scattered light intensity changing with time.Furthermore, the microprocessor used the algorithm based on MIE theory to obtain the equivalent particle size and the number of particles with different particle sizes per unit volume.

Data interface: 2 pins are serial data communication interfaces, which adopt general asynchronous transceiver protocol (UART);1 pin is the control signal interface, using high and low level control, the average of all electricity is 3.3VTTL level.

Note: SET=1 module works in the continuous sampling mode. After each sampling, the module takes the initiative to upload the sampling data. The sampling response time is less than 600 milliseconds, and the data update time is less than 2 seconds. SET=0 module enters low power standby mode
