Additional Details

The TSOP6938TR operates at a carrier frequency of 38 kHz. The internal filter effectively blocks out ambient light and other sources of infrared radiation that could interfere with the desired signal. The module is housed in a compact epoxy package that provides protection against physical damage and environmental factors. The output signal is an active-low signal. When an infrared signal is detected, the output goes low; otherwise, it remains high. This active-low output is compatible with TTL and CMOS logic levels, making it easy to interface with microcontrollers and other digital circuits.
