This module is based on HR202 resistive humidity sensor, which exposes excellent linearity, has a wide measurement range and a low power consumption. The module features both a power output indicator LED and a digital output indicator.

This module is ideal for custom humidity sensing applications, and can be used in fields like meteorology, storage facility humidity control, textile industry and other applications which need ambient humidity monitoring.

The output is available both as an analog output and as a digital output obtained using a comparator based on LM393 integrated circuit.

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.
