Rain / Raindrop Detection Sensor Kit with Relay Module

The Rain/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.

Features :

1. The LM393, use of the wide voltage comparator
2. Provide both digital and analog output
3. Output LED indicator
4. Compatible with Arduino
5. TTL Compatible
6. The sensor uses the high-quality FR – 04 double material, the large area of 5.5  x  4.0 cm
7. Treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance
8. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
9. With potentiometer sensitivity adjustment
10. The output format: digital switch output (0 and 1) and analog AO voltage output;
11. Has a fixed bolt hole, convenient installation
