IR sensor (pack of 2)

The IR sensor is used to sense if there is some sort of obstacle in its line of sight. It does that by sending an IR (infrared) light from the transmitter end, which isn’t visible to the normal eyes, and then, if there’s some sort of obstacle, then the light is reflected back and is detected by the receiver. The sending process is continuous and as soon as the obstacle is detected, we can use it to perform our required output. The Detection Range of an IR sensor is 2 to 20cm & the Detection Angle is 30° to 40°
