PM2.5dust sensor module concentration sensor module is the same with the single chip. CHARACTERISTICS OF DUST CONCENTRATION SENSOR structure of the dust concentration sensor is shown in Figure The structure of the dust concentration sensor The function and pin of the dust sensor is shown in Table signal from the single chip, the dust sensor controls the C. DS1820 temperature sensor module The data collection of the dust concentration is the key of When the power turns on, the dust monitoring sensor scenic area, and the sensor is opened to collect and transmit 	./cache/work_m3ktnhp6ojf3fkul4nelspot4a.pdf	./txt/work_m3ktnhp6ojf3fkul4nelspot4a.txt
