TSOP Infrared Receiver Module
IR Signal Detection Remote Control Interface Digital Output Sensor
The TSOP Infrared Receiver Module is an electronic sensor designed to receive infrared signals from remote controls and convert them into digital signals for microcontrollers. These modules are widely used in TV remote systems, home automation, robotics, and Arduino-based IR communication projects.
TSOP modules typically work with infrared signals modulated around 38 kHz, allowing them to filter noise and accurately detect commands from IR transmitters.
