Small board pcb size: approx. 32 cm x 15 cm 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 x 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.
