Additional Details

The PT501B typically operates at a carrier frequency of 38 kHz, which is a common standard for IR remote control signals. It outputs a digital signal that can be easily decoded by a microcontroller or other digital logic circuitry. The module is often supplied in a three-pin package (Vcc, Ground, Output). The operating voltage typically ranges from 2.7V to 5.5V. Care should be taken to shield the module from direct sunlight or other strong IR sources to prevent interference.
