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: Approx. 3.2 cm x 1.5 cm The LM393, use of wide voltage comparator.
