TSOP-1738 IR Receiver (Infrared Receiver)

The TSOP1738 is a commonly used infrared (IR) receiver module designed to receive modulated infrared signals typically used in remote control systems such as those for TVs, air conditioners and other consumer electronics.

Here are the key features and specifications of the TSOP1738 IR receiver:

Key Features:

• Carrier Frequency: It is tuned to receive infrared signals at a carrier frequency of 38 kHz. This is the standard frequency used by most infrared remote control devices.
• Output: It provides a digital output signal (active low) when it detects an infrared signal modulated at 38 kHz.
• Low Power Consumption: The TSOP1738 is designed to consume very little power, making it ideal for battery-powered devices.
• Compact Design: It is a small, lightweight component, making it easy to integrate into various devices.
• Easy Integration: It can easily interface with microcontrollers like Arduino or Raspberry Pi for various IR-based applications.

Working Principle:

• The TSOP1738 receives the infrared signals from a remote control (or other IR devices), which are modulated at a 38 kHz frequency.
• When it detects the modulated IR signal, the module demodulates it and outputs a digital signal that can be read by a microcontroller (e.g., Arduino, ESP32, etc.).
• If no signal is detected, the output remains in the high state, and when the IR signal is received, it goes low.

Applications:

• IR Remote Control: Used to receive commands from remote control units.
• IR Data Transmission: Used in wireless communication systems, such as data transfer between devices.
• Robotics: Can be used for line-following robots or object detection.
• Security Systems: Can be used in motion detection and other IR sensing applications.

Pinout:

• Vcc (Pin 1): Supply voltage (usually 5V or 3.3V, depending on the model).
• GND (Pin 2): Ground.
• OUT (Pin 3): The output signal, which goes low when an IR signal is detected.

The TSOP1738 is widely available and can be used in a variety of projects involving infrared communication or remote control.
