Circuit detectors and sensors based electronics projects
Circuit detectors and sensors based electronics projects like: metal detectors circuits, smoke detectors circuit, water detector circuit, light detector and other based sensors projects.
Using this circuit diagram can be made an electronic switch that allows actuation of a relay. This control circuit is triggered using a light source which will act a Photoresistor.
The infrared emitter can be used as a control device for the infrared receiver.
It works with two batteries of 1.5 V or a 3 V lithium button cell type.
