Rain Detector With IC 555
Rain detector with IC 555 is a simple alarm that can be used to find out it was raining. Rain detector with IC 555 in principle this is an astable multivibrator 555 which is prepared by IC 555 with a sensor attached that can detect water. Astable multivibrator with the 555 is set in the audio frequency with a frequency of 1 KHz. Using Rain Detector circuit 555 can be disupplay with voltage source that is free enough from 5-15 VDC. In the application circuit rain detector with IC 555 this can be mounted motor, car or other object that we want to protect from rain.
Schematic Circuit Of Rain Detector With IC 555
Water sensor used in the circuit of rain detector with IC 555 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 this sensor is to conduct electrical current very well when the surface is exposed to water even a little. Hopefully useful …
