The rain sensor (weather module, sensor steam, water, rain drops) for Arduino is a sensor module, which actually responds to drop. The IC op amp LM393 processes the signal and transmits it to the master controller in digital and analog form. To use Sensor need
  • to collect on the basis of its layout
         
    • connect the power,    
    • to connect to the controller,
     
  • to place the sensor in the measurement environment.
  • to record the controller a special program that allows you to work with the sensor.
You can start working.

Alarm work rain sensor (weather module) for Arduino :

  • The green LED on the board lights up when power is applied to the sensor.
  • The red LED that lights up when the sensor transmits the data to the controller.
Rain sensor, weather module has two interfaces for connecting external devices:
  • to connect to the power supply and microcontroller uses a 4-pin male interface. Designation of contacts: VCC - power supply; GND - common contact; D0 - digital output; A0 - analog output;
  • to connect the sensor using 2-pin male interface.
Manage rain sensor :
  • from the Arduino controller,
  • from other control microprocessor with special programs.
The board is a variable trimmer, which is used to adjust the sensor threshold (sensitivity). Using the rain sensor (weather module) for Arduino :
     
  • to measure the amount of precipitation;
  • to save water. The sensor interrupts the programmed watering cycle in the accumulation of a certain level of precipitation;
  • to control the operation of the wiper. In accordance with the number of raindrops on the windshield, rain sensor activates the windshield wipers and sets the mode of their work.
