Raindrops module/rain sensor module/large rain sensor module weather module

Raindrops module   Features:   100% Brand New. Product use: rain, rain sensor, can be used for all kinds of weather monitoring, and translated into output signals and AO. The sensor USES the high quality FR - 04 double material, large area of 5.5 * 4.0 CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance; The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma; With potentiometer sensitivity adjustment The working voltage of 3.3 V to 5 V The output format: digital switch output (0 and 1) and analog AO voltage output; Has a fixed bolt hole, convenient installation Small board PCB size: 3.2 cm x 1.5 cm The LM393, use of wide voltage comparator Note: the line's color may be different from picture show, but we sure function is same! Function is introduced:
Connected to 5 v power supply, power indicator, no water droplets on induction plate, the DO output high level, switch indicator light out, drop a drop of water on, the DO output for the low level, the switch light is lit,Brush away the water droplets, again to return to, the output high level... AO analog output, which can be connected to the microcontroller AD mouth detection drops of rainfall in the above size. DO TTL digital output also can connect to the single chip microcomputer detect whether there is rain. Connection mode:
1. VCC: positive (3-5 v) 2. GND: connect power anode 3. DO: TTL switch signal output 4. AO: analog signal output                      Shipping
