TSOP1838 - Infrared Sensor Remote Receiver 38kHz

TSOP1838 Infrared Sensor Module - 38kHz IR Receiver

The TSOP1838 is a highly integrated infrared remote control receiver module, designed for robust performance in various environments. This compact module combines a PIN diode and a preamplifier. It is specifically tuned to detect 38 kHz infrared waves, making it ideal for standard IR remote control signals. Its output is active low, providing a +5V signal in its off state. Advanced features like a bandpass filter, integrator, and automatic gain control effectively suppress disturbances from ambient light sources. Enhanced immunity against electrical field interference and a short settling time after power-on ensure consistent and accurate IR signal detection. It's a dependable choice for any project requiring precise infrared remote control capabilities.
