Rain / Snow sensor for Arduino

Works by detecting liquid on the surface of the board with exposed tin traces and changes the level at the
output which can then be processed with arduino or Raspberry pi.

1. 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;
2. With potentiometer sensitivity adjustment;
3. The output format: Digital switch output (0 and 1) and analog AO voltage output;
4. Has a fixed bolt hole, convenient installation;
5. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
6. The LM393, use of wide voltage comparator;
7. The working voltage of 3.3 V to 5 V
