For control of air purity laser dust sensor. Designed to measure PM2.5 and PM10, it allows detecting particles with a diameter greater than 0.3 μm. It has a fan that sucks air. The system is powered by a voltage of 4.7 V to 5.3 V, communicates with Arduino or Raspberry Pi via UART signal or PWM. The sensor has seven pins. If the sensor is connected to Arduino or other devices operating with 5 V voltage, you should use a voltage converter.
