Video shows the usage of TempGP rain sensor. If water or rain hits the senor plate the headlights will be automatically activated.   Water triers the relay. This board can be used as a building block to control headlights in cars, close the rooftop in convertibles in case there is rain, shut off water of the washing machine if  there is a leak, start water pump in the basement if there is water from rain etc.  Basically we built the board to be a building block for your projects!!! Additionally to the rain sensor there is timer delay button. We dont really know why we added it there but if you press button the relay will be kept closed for 20 sec. You can use it as timer or something :)
