Rain Detector Using 555 is a simple alarm that can be used to find out it was raining. In principle, Rain Detector Using 555 is an astable multivibrator which is prepared by IC555 with installed a sensor that can detect water. Astable multivibrator with the 555 is set in the audio frequency with a frequency of 1 KHz. The series of Using Rain Detector 555 can be disupplay with a voltage source that is free enough from 5-15 VDC. In the application circuit Rain Detector Using this 555 can be mounted motor, car or other object that we want to protect from rain.
Water sensors that are used in circuit 555 Rain Detector Using this we can make yourself degan a PCB that we make the path as shown in the image above or as disclosed from the image above is by using aluminum foil taped to a board or boards that are plastic insulator . The important principle of the sensor is to conduct electrical current very well when the surface is exposed to water even a little. Hopefully useful ...
