TSOP1838 - Infrared Sensor

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. It combines a PIN diode and a preamplifier within a single, compact package. This sensor is specifically tuned to detect infrared waves with a center frequency of 38 kHz, making it ideal for standard IR remote control signals. Its output is active low, providing a +5V signal in its off state. To ensure reliable operation, the TSOP1838 incorporates advanced features like a bandpass filter, an integrator stage, and automatic gain control. These mechanisms effectively suppress disturbances from ambient light sources such as sunlight and fluorescent lamps. With enhanced immunity against electrical field interference and a short settling time after power-on, this module delivers consistent and accurate IR signal detection. It's a dependable choice for any project requiring precise infrared remote control capabilities.
