Basics of IR Sensor | IR LED Pin Diagram & Working Nov 03, 2020The IR rays from the IR LED in the circuit are shown in the camera. Pin Diagram of IR LED. An IR sensor is an electronic device that detects IR radiation falling on it. audio musical notes can be generated and heard up to a distance of 10 metres. The IR music transmitter works off a 9V battery, while the IR music receiver works off Interfacing E18-D80NK IR Proximity Sensor with Arduino The E18-D80NK is an advanced low-cost IR Proximity Sensor with an obstacle detection range of 3 cm to 80 cm. Circuit Diagram for Interfacing E18-D80NK Sensor with Arduino. This is a start guide for using the GP2Y0A02YK0F distance sensor with Arduino and TFT Touch Screen.

Before starting, turn of all power from your Arduino board to prevent any electrical hazards. Now let's get onto the wiring of this proximity sensor. First, connect the positive pin (red wire) of the sensor to 5v (+5 volts) on the Arduino. Second, connect the ground pin (black wire) of your sensor
