TSOP1738 IR Receiver Plastic (Through Hole)

The tsop1738 is a reliable IR receiver tsop 1738 module featuring an integrated PIN photodiode and preamplifier in a compact plastic through-hole package. It is optimized to receive only 38kHz modulated infrared signals, ensuring stable performance even in environments with sunlight or fluorescent lighting.

The output is active low, meaning the signal goes LOW when a valid IR signal is detected. Internal circuitry such as a bandpass filter, automatic gain control (AGC), and integrator stage effectively suppress ambient light interference, making it superior to basic IR sensors.

How TSOP1738 Works

When an IR source emitting 38kHz modulated signals is detected, the TSOP1738 processes the signal through its internal amplifier and filter stages. The decoded output is then provided as a clean digital signal compatible with TTL and CMOS logic, making it easy to interface with Arduino, Raspberry Pi, PIC, and other microcontrollers.
