Video Demonstration An IR proximity sensor is a device which detects the presence of an object or a human when it is within a predetermined range from the sensor, through reflected infrared beams. Three useful proximity sensor concepts are explained here, the first concept is based on an ordinary opamp LM358, the second one using […]
