Additional Details

The IRM-H236T/TR2 typically operates at a carrier frequency of 36 kHz. The supply voltage is typically 5V, but some versions may operate at 3.3V. The output signal is a logic low when an IR signal is detected and a logic high when no signal is present. A decoupling capacitor is usually recommended close to the power supply pin to improve noise immunity. The sensing range depends on the transmitter power and environmental conditions. Ensure the IR transmitter's wavelength matches the receiver's sensitivity range. This module effectively detects and decodes infrared signals, making it a critical component in many remote control applications. The viewing angle impacts the effective range of the IR receiver. It has a demodulator built into the component. The signal is received through the plastic case.
