PM2.5+Temperature and Humidity Two-in-one Sensor Detector PMS5003T G5T High Precision Professional Sensor

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. Pin Description: VCC: Power +5V GND: Power supply- SET: Set the pin/TTL level @3.3V high or floating to normal operation, low level to sleep state RXD: Serial receiver pin / TTL Level @3.3V TXD: Serial transmit pin / TTL level @3.3V RESET: Module reset signal / TTL level @3.3V, low reset
