User Guide / How to Use

Using the TSOP1738 IR Receiver Module is simple. Connect the VCC and GND pins to the power supply (3.3V or 5V depending on your microcontroller), and the OUT pin to any digital input pin on your board (like an Arduino or ESP32). Using an IR remote control, you can send signals to the module. The output pin will go LOW whenever a valid IR signal is received, which can then be decoded using an IR library in your microcontroller’s development environment.

Libraries such as IRremote for Arduino simplify the process of receiving and decoding IR signals. The module works effectively within 5 meters when paired with a standard IR remote control.

Frequently Asked Questions (FAQs)

• Is the TSOP1738 compatible with Arduino? Yes, it is fully compatible with Arduino and other microcontrollers like ESP8266, ESP32, and Raspberry Pi.
• What is the frequency of the TSOP1738? It is designed to receive IR signals modulated at 38 kHz, which is standard for most remote controls.
• Can I use this sensor outdoors? While it has high ambient light immunity, very bright sunlight can reduce its performance. It is recommended for indoor or controlled lighting conditions.
• How do I know if the sensor is working? You can view the output using a serial monitor in your development board, or connect an LED to visualize the signal reception.
• What IR remotes work with this sensor? Most TV, DVD, and appliance remotes using 38 kHz IR signals are compatible.
