Additional Details

The TSOP85238HFTR operates at a carrier frequency of 38 kHz. It is designed to receive infrared signals modulated with a Pulse Code Modulation (PCM) scheme. The output of the module is an active low signal, meaning it outputs a low voltage when an infrared signal is detected. The module is typically powered by a 3.3V supply, but it can operate with voltages ranging from 2.0V to 3.6V. This device is designed for high data rate applications, enabling faster communication between the remote control and the controlled device. The detection range is dependent on the transmit power of the remote control and the ambient conditions. The epoxy package provides mechanical protection and helps shield the internal components from external interference.
