Additional Details:

The IRM-3638M-X typically operates on a 5V power supply. The output is usually a logic-level signal that indicates the presence or absence of a valid IR signal. The receiving angle is an important parameter that determines the effective range of the remote control. External components, such as a decoupling capacitor, are recommended for stable operation. The module's output signal is typically active low, meaning the output is low when a valid IR signal is detected. The peak wavelength is usually 940nm.
