The Arduino Uno Infrared Sensor Receiver Module detects infrared (IR) signals emitted by IR transmitters. It typically includes an IR receiver and a circuit to demodulate the received signals, ...

IR Sensors Each IR sensor has a transmitter (IR LED) and a receiver (Photodiode). When an object blocks the IR rays, the Arduino detects a voltage change and processes it as an event.

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

[Maker 101] gave the Arduino an infrared sensor which can pick up signals from a simple IR remote control. It can be driven backwards and forwards or turned left and right.

In this tutorial, we are going to interface 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.

This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

Presence of doctor is essential for proper patient care. But he cannot be present on each and every place to provide medication or treatment. So remote monitoring of a patient is the right solution.
