The design of IR Transmitter and Receiver circuit is explained here. The modulated signal can only be demodulated by the appropriate IR Receiver. So, in order to prevent interference and false triggering, we will modulate the infrared light. There are many sources of infrared light like sun, light bulbs, all hot items and even human body. The wavelength of Infrared Rays is greater than that of Visible light and hence they are invisible to human eye.Ī typical IR LED emits infrared rays in a wavelength range of 740 – 760 nm. IR LED is a special type of LED that emits Infrared rays of the Electromagnetic Spectrum.

Also the Resistor R and Capacitor C are only used to suppress the power supply disturbances. The IR Receiver will receive this modulated signal and demodulates it and sends it to the Microcontroller.įrom the image it can be observed that the output of the IR Receiver is directly connected to the Microcontroller and there is no need for any extra interface. In the image, the IR Transmitter emits Infrared light modulated at a particular frequency. The following image describes the block diagram of the IR Transmitter and Receiver. Some of the other characteristics of TSOP 1738 are high immunity to ambient light, active low output, low power consumption, continuous data transmission and compatibility with TTL as well as CMOS.Ī typical application circuit of TSOP 1738 IR Receiver (or any IR Receiver for that matter) will consists of an IR Transmitter (IR LED), IR Receiver (TSOP 1738) and a microcontroller. The following image shows the pin out of TSOP 1738. TSOP 1738 has three pins namely GND, VS and OUT. TSOP 1738 in particular supports a carrier frequency of 38 KHz and the output of this IR Receiver can be directly connected to a microcontroller or a microprocessor.
#CPS IR RECEIVER SERIES#
TSOP17XX series of IR Receivers are very common for all types of transmission codes supporting different modulating techniques like RC6, RC5, NEC, Sony, etc. It consists of Photo Detector, Gain Control, Band Pass Filter, Demodulator and a Pre – amplifier in a single package. TSOP 1738 is an IR Receiver for IR (Infrared) remote controls.
#CPS IR RECEIVER CODE#
10 nF Ceramic Capacitor (Capacitor Code 103)Ĭomponent Description TSOP 1738 IR Receiver.1 nF Ceramic Capacitor (Capacitor Code 102).The circuit is divided in to IR Transmitter circuit and IR Receiver circuit. The IR Transmitter and Receiver circuit diagram is shown in the following images. The circuit diagram, components and the working is explained in the subsequent sections. For this project, we have used TSOP 1738 IR Receiver to receive infrared signals and a simple IR LED to transmit infrared signals. The aim of the project is to explain how Infrared (IR) communication works with the help of simple hardware. In this project, we have demonstrated the functioning of a simple IR Transmitter and Receiver using 555 Timer. Some embedded projects also consists of IR Transmitter and Receiver Modules where they can be used as proximity sensors or distance measurement sensors.
#CPS IR RECEIVER TV#
The handheld remote control of the TV consists of IR Transmitter and the IR Receiver is placed at the TV. The most common use of Infrared (IR) communication is remote controls of different appliances like TV’s. IR Communication generally comprises of IR Transmitter and Receiver. IR communication is an easy to use and inexpensive wireless communication.
