How to Make an IR Remote Tester





Introduction: How to Make an IR Remote Tester

IR Remote Tester is simple circuit that can be a good tool to check whether a remote hand set is working or not. It uses the commonly available IR sensor TSOP 1738.The IR sensor has a PIN photodiode and an FET signal amplifier enclosed in an Epoxy case.

Now I am going to instruct how to make an IR Remote Tester with less number of components.

Lets Get Started..

Step 1: Components Required

LED - 1 [ Amazon / ebay ]

Tsop 1738 [ IR receiver 38kHz] - 1 [ Amazon / ebay ]

IC 7805 -1 [ Amazon / ebay ]

9v Battery and clip -1

Resistor (100 Ohm) -1

Breadboard - 1 [ Amazon / ebay ]

Male to Male Jumpers [ Amazon / ebay ]

Step 2: Circuit Construction

Connect IC 7805 Ground,Output pins to GND, Vs of Tsop1738 respectively.

Connect a 100 Ohm resistor from Vs pin of tsop1738 to +ve pin of LED and -ve pin of LED to output of tsop1738.

Connect 9V battery +ve to Input pin of IC7805 and -ve of battery to GND of 7805

Circuit Construction Completed ..

When you press any button of IR remote , the LED in the circuit blinks.

Datasheets of IC7805 , TSOP 1738 is attached.

Step 3: Construction and Testing

    Or you could just use your phone's camera...

    True, but this can be a great one-day school project: cheap, easy and quick to make and test.

    I can't argue with that, I'm just saying that there is a more practical way to check if your remote works, still a good instructable for people interested in or learning electronics, nonetheless.

    I agree with you. Actually, I show that "trick" to my students whenever there's a doubt about a IR remote in the high-school I teach in (I'm not an electronics teacher).
