DescriptionInfrared Receiver: TSOP1738 is designed to receive infrared signals. It is sensitive to IR wavelengths commonly used in remote control systems.Plastic Package: The sensor is housed in a plastic package, which provides physical protection and enhances its durability. The plastic package allows the sensor to be easily integrated into various devices.Carrier Frequency: TSOP1738 is typically used for IR signals modulated at a carrier frequency of 38 kHz. It is widely compatible with remote controls that use this frequency.Demodulation: The sensor demodulates the received infrared signals, separating the carrier frequency from the data signal. This demodulated signal can then be processed by microcontrollers or other digital circuits.Output: The sensor provides a digital output signal, indicating the presence or absence of the modulated IR signal. When a compatible IR signal is received, the sensor output goes low, indicating the reception of the signal.Voltage Supply: TSOP1738 typically operates at a voltage supply of around 5V DC. It is essential to provide the sensor with the appropriate voltage for reliable operation.Applications: Commonly used in infrared remote control systems for TVs, air conditioners, audio equipment, and other electronic devices. It is also used in automation and robotics for object detection and proximity sensing applications.
