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.

I found that we could get the radio to reach the length of a 60ft bowling alley, but it worked best with one long range version as the receiver, and a standard module for transmitting.

The third-generation smart home hub features an LCD display, an infrared transmitter and receiver, four programmable shortcut buttons, and a rotary knob.

Wi-Charge’s AirCord technology uses infrared lasers to beam power from its R1 wireless power transmitters to a receiver within line of sight.

This paper presents a miniature inductorless impulse-radio ultra-wideband transmitter-receiver and radar for wireless short-range communication and vital-sign sensing. The all-digital transmitter ...

Windows includes IrDA infrared support. The drivers are installed, but they are inactive. You need to activate them in you want to send/receive files using Infrared.

Apart from the Arduino UNO, the circuit consists of two more primal parts – an infrared emitter and an infrared receiver, which are as follows.

It does feel like a chicken-and-egg situation. A single transmitter can serve multiple devices, but you need devices with infrared receivers to make it worthwhile to buy a transmitter.

The main idea behind this paper is to generate musical notes by infrared radiations. The infrared radiations are transmitted and received by IRLEDs and phototransistor respectively. This paper ...
