TSOP1738 Infrared Receiver Sensor 38kHz DIP3 (TSOP1738 IR Receiver)
The TSOP1738 IR Receiver is a highly sensitive infrared sensor designed to receive modulated IR signals at a frequency of 38kHz. It integrates a PIN photodiode, preamplifier, and signal processing circuitry in a single compact package, allowing it to decode IR signals from remote controls and transmit them as digital output.
This sensor is widely used in India for remote control systems, robotics, and embedded electronics. It is specifically tuned to 38kHz, which is the standard frequency used by most TV, AC, and home appliance remotes, ensuring accurate and noise-free signal reception.
