This infrared transmitter can be used with this infrared receiver. This transmitter uses. The modulated signal is produced by comparison of an audio signal with a triangle signal of high frequency ...

This circuit has been designed to complement the ‘Simple IR Transmitter’ and to decode its transmitted signals. The similarity to the transmitter can be clearly seen: the received data is decoded by a ...

This project documents the design and implementation of a low-cost infrared (IR) transmitter and receiver system suitable for industrial wireless communication. Developed using off-the-shelf ...

This infrared alarm barrier can be used to detect persons passing through doorways, corridors and small gates. The transmitter emits a beam of infrared light which is invisible to the human eye. The ...

Abstract: The architecture of a low-complexity ultra wideband (UWB) impulse radio (IR) transmitter and receiver circuit, aimed for low-cost applications is presented. To project a simple and ...

This circuit restores the original modulation of the signal received from the remote-control unit, which was demodulated by the receiver unit at the other end of the extender (see ‘Receiver for ...

A stick for the blind proposed here is an assistive device that helps visually impaired individuals navigate safely. It features an infrared (IR) sensor that detects obstacles and activates a buzzer ...
