【Abstract】 This paper introduces the design idea and method of PM2.5 multifunctional detector in detail. The microprocessor of the detector adopts 32-bit RAM microprocessor. The detector can accurately detect the concentration of PM2.5, PM1.0, PM10 and other dust particles in the air. At the same time, it can detect the temperature and humidity of the environment and the comprehensive quality of VOC air, and realize the power supply function of lithium battery. The PM2.5 sensor used in the detector is a laser dust particle sensor, which has the advantages of accurate detection, strong anti-interference ability, long service life and high cost performance.更多还原
