Raindrops Detection sensor module can be used for both detecting rain and for measuring the intensity of rainfall.

It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analogue pin. A completely dry board, for example, will cause the module to output 5V.

  • The LM393, use of the wide voltage comparator
  • Provide both digital and analog output
  • Output LED indicator
  • The sensor uses the high-quality FR – 04 double material, the 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 output format: digital switch output (0 and 1) and analog AO voltage output
