  • The comparator output, the signal is clean, waveform, driving ability over 15mA
  • Distribution bit to adjust the sensitivity
  • Operating voltage 3.3V-5V
  • The output in the form: digital switching outputs (0 and 1) and analog AO voltage output
  • A fixed bolt hole for easy installation
  • Voltage: 5V
  • Wide voltage LM393 comparator
  • Power indicator, the output signal LED indicator.
  • TTL-level output, TTL output valid signal is low. Driving capability 100mA so can directly drive relays, buzzer, a small fan, and so on.
  • Sensitivity can be adjusted via potentiometer
  • LED lights up when there is no rain output is high, raindrop up, the output ground level, LED light.
  • Raindrops and control panels are separate, easy to wire leads.
  • A large area of rain board, more conducive to detect rain.
  • Board with positioning holes to facilitate installation
  • Small board PCB size: 3.2cm x 1.4cm


Connection mode:

Pin, Control, or Indicator
Description
VCC
+5 Volts Power Source
GND
Ground or negative power source
DO
Digital Output. Goes low when moisture exceeds set threshold.
A0
Analog Output – Zero to five volts. The lower the voltage, the greater the moisture.
Power LED
Indicates that power is applied
Output LED
Illuminates when moisture has exceeded the threshold set by sensitivity adjustment
Sensitivity Adjustment
Clockwise is more sensitive. Counterclockwise is less sensitive.


Package Includes:

The Raindrop Detection Sensor module is an easy-to-use and low cost drop recognition sensor. The sensor works through a series of exposed parallel traces on board which produces electrical variations when drops or water volume changes. By using microcontrollers or ADC ICs (Arduino and PIC) it's fairly easy to convert the analog output from the sensor to digital values.

Easy to complete water to analog signal conversion and output analog values can be directly read Arduino development board to achieve the level alarm effect. Rainwater can be used to detect water level detection

This can be directly read by a Raspberry Pi or Arduino or a comparator circuit if you wish to use it as a rain detection alarm. It can be used to monitor a variety of weather conditions.
