TSOP17XX (TSOP) is a commonly used IR receiver for Infrared PCM remote control systems. It is used in TVs, DVD Players, Burglar Alarms etc. Download. This general purpose ultra-thin 38Khz universal infrared remote control, uses NEC encoding format. TSOP Sensor: The TSOP is a infrared receiver tuned to. The TSOP Sensor with Robosoft Systems is a miniaturized receiver for infrared remote control systems.

Noises and Data signal tso1738 distinguished by using carrier frequency, burst length and duty cycle. Use Transistor in between, like shown here. How can I use IR sensor as distance measurement? The usual places I order parts Mouser, Digikey,etc doesn’t have anything close.

Line Follower Robot using Arduino. The moment I press the remote button, the receiver should ri and disconnect it when I release the button. IR Transmitter and receiver are used to control any device wirelessly, means remotely.


So basically use it as a remote switch that only works when a button is pressed. Leave the Transmitter part as it is, just change the sebsor part according to your requirement. There is no component name TSOP I have one that isn’t working. Can u suggest me a circuit in which both the tsop and irled use single powersource and the readings of tsop is measured by arduino. I have only one question, what is the emitor voltage for the Q1 transistor?

IR Transmitter and Receiver Circuit Diagram

If I were to have multiple transmitters with receivers in the same room all using the TSOP17xx’s as receivers at different frequencies, do you think they would cross-talk?

The signal from AGC is passed to a band pass filter to filter undesired frequencies. A uF capacitor is connected across the supply to provide the constant supply to the circuit, without any ripple.

The demodulated output signal can directly be decoded by a microprocessor.

If you use up to 20 red led connected in series. The junction points are missing and the Q1 emitter is on the wrong side, connected this way, it will not work. Sensir to how much distance between sender and receiver it will work?? There are lot of Alarm circuits on the site, please check below link: A 10k resistor is used for provide proper biasing to transistor and a ohm resistor is used at LED for limiting the current.

Check circuit at Receiver part, connect transistor BC properly. Really it is too useful for all students. If you want to senssor an intellectual property right violation of this product, please click here.

Hello creator, good job Just please correct the wiring of the receiver part. SCS GurgoanHaryana 3. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. PNP transistor behaves opposite to the NPN transistor, it acts as open switch when a voltage applied to its base and acts as closed switch when there is no voltage at its base. C1 is connected in receiver circuit for the same reason as we connected C3 uF in Trasnmitter across the supply, to provide the constant supply without any ripple.


Circuit Diagram is correct and its a PNP transistor. Log in or register to post Comment. With respect, I don’t think the article is clear on this point. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low.

Looking forward to using this for a fun project.


Thank You for Visiting Teop1738 Store. Sir can use ldr in the transmitter section that will power the circuit when jr means when there is no light then the circuit will start emitting rays. Hello sir I have a problem regarding the receiver I use sliding switch instead of tact switch but when I switch on the transmitter for very long the led of the ir receiver will only stay for about 1 second how can i fix this?

Can is it possible to trasmitte addree of perticular button through IR Transreceiver?

I have a problem when create in proteus.
