What is a TSOP1738?

TSOP1738 is the standard IR remote control receiver series, supporting all major transmission codes. The sensor can be used for Proximity detection application along with a IR led in robotics and security systems. It receives IR signal at 38khz frequency.

How do I connect my Arduino to IR sensor?

The connections for the IR sensor with the Arduino are as follows: Connect the negative wire on the IR sensor to GND on the Arduino. Connect the middle of the IR sensor which is the VCC to 5V on the Arduino. Connect the signal pin on the IR sensor to pin 8 on the Arduino.

How do I check my TSOP1738?

Give power supply to pin 2 with the help of resistor and ground pin 1. Set your multimeter in voltage range at 20V. Now put positive terminal of your multimeter on pin 3 of TSOP1738 and ground the another end of multimeter. Now whenever you press any button on remote you will see variation in multimeter reading.

What is the difference between Arduino and tsop1738?

Where Arduino is the main microcontroller of the project that’s controlled all other components. TSOP1738 is an IR Receiver sensor, that can detect 38 kHz IR frequency coming from the IR remote. Here we have used a remote to control home devices. A Relay Module is an electrically operated switch.

How does a tsop1738 work?

TSOP1738 is an IR receiver with an amplifier that acts as a switch and converter within a circuit. It has one input and output which only acts on the base of the input IR signal. The basic purpose of TSOP1738 is to convert the IR signal to electric signals. Every IR receiver has a special frequency to operate.

How does the tsop-1738 IR receiver sensor work?

The TSOP-1738 is an IR Receiver Sensor, which can be used to receive IR signals of 38Khz. The sensor operates on 5V and consumes around 5mA to operate. Normally the signal pin (pin 3) IC is connected to a microcontroller to analyse the IR signal received.

How to connect TSOP 1738 to Arduino with hex code?

Connect 330 Ωresistor to the data pin of TSOP 1738. Then connect another leg of the resistor to Arduino pin 2. Now open the serial monitor and press the buttons from remote. You’ll find the HEX code of each button on the serial monitor. Note down the HEX code of the buttons of your choice.
