Additional Details
The RPM7136-H4R typically operates at a supply voltage of 5V. It is designed to receive infrared signals modulated at a carrier frequency of approximately 36kHz. The module outputs a digital signal corresponding to the decoded remote control commands. An external pull-up resistor is generally recommended for the output pin. The operating temperature range usually spans from -25°C to +85°C. The Automatic Gain Control (AGC) feature automatically adjusts the gain of the internal amplifier to compensate for variations in signal strength, ensuring a consistent output level.
