Additional Details

The IRM-3638TF4 operates on a 5V supply. The output is typically high and goes low when an IR signal is detected. The detection range depends on the transmitting power of the remote control and environmental conditions. The module includes a bandpass filter centered at 38kHz to reject unwanted signals. The datasheet provides pinout information, electrical characteristics, and application circuit examples. Always consult the datasheet for specific operating conditions and performance details to ensure optimal performance and reliability. The receiving angle is specified in the datasheet, affecting the positioning of the remote control. Specific shielding techniques might be needed in noisy environments.
