Uses:Humidity detection , humidity sensors , humidity detection Module Features : 1 , using high-quality HR202 humidity sensor ; 2 , the comparator output signal is clean, good waveform , driving ability , more than 15mA; 3 , adjust the temperature distribution position detection threshold; 4 , the working voltage 3.3V-5V; 5 , the output form : DO digital switching outputs ( 0 and 1 ) and AO analog voltage output; 6 , a fixed bolt holes for easy installation; 7 , a small PCB board size : 3.2cm x 1.4cm; 8 , using a wide voltage LM393 comparator. Product wiring instructions : 1, VCC positive power supply 3.3-5V 2, GND power supply is negative 3, DO TTL switching signal output 4, AO small plates analog output ( voltage signal ) Module for use 1, the humidity sensor module is sensitive to environmental humidity , generally used to detect ambient humidity ; 2, by adjusting the potentiometer , for detecting the humidity can change the threshold ( i.e. the humidity control ) , such as the need to control the ambient humidity of 60% , then the corresponding module is transferred to the green light and humidity environment , DO high power output when flat , humidity values below this setting , high output, the green light does not shine ; 3, DO output can be directly connected to the microcontroller through the microcontroller to detect high and low , thereby detecting the humidity changes in the environment ; 4, DO output of the relay module can directly drive the shop , which can form a humidity switch , control-related equipment to work in the right environment ; 5 , small plates AO analog output modules can be connected OUR AD through the AD converter , you can get a more accurate numerical ambient humidity .
