Snow & Rain Detection Sensor Module

Easily detect rain or snow with this Arduino module. The large plate simply needs a drop of water to connect the circuit. The more water there is on the plate, the less the resistance. Robot kits , rain , rain sensor , can be used to monitor a variety of weather conditions , and turned into several fixed output signal and AO . 1, the sensor uses a high -quality double-sided FR-04 materials , the large area of 4.0CM, and nickel -plated surface , effective against oxidation, conductivity, superior performance and lifetime areas ; 2 , the comparator output signal clean waveform is good , driving ability, than 15mA; 3 , power bits adjust the sensitivity ; 4, Working voltage 3.3V-5V 5, the output format : Digital switching output ( 0 and 1 ) and analog voltage output AO ; 6, with bolt holes for easy installation 7 , a small board PCB size : 3.2cm x 1.4cm 8 , using a wide voltage LM393 comparator
