Laser sensor of dust /particle concentration PM2.5 - PMS5003

The sensor measures the coefficient of PM2.5, that is, the number of so-called dust suspended in the air. They are contaminants which are harmful to the environment and human health. The device is powered with 5V, the data passes through the communication, serial interface UART (RX,TX). The kit includes: sensor, wire and plate for connecting the signals to any microcontroller, e.g.an Arduino.

The product is compatible with Arduino
