IR Receiver Module TSOP4838 DIP-3 Remote

The TSOP4838 is an infrared (IR) receiver module designed for detecting and decoding IR signals typically used in remote control systems. It operates at a 38 kHz carrier frequency, which is standard for many remote-controlled consumer electronic devices. This module is part of the DIP-3 (Dual Inline Package) series, known for its simple integration into various electronic circuits with a three-pin configuration.Featuring a sensitive photo detector and signal processing circuit, the TSOP4838 is highly effective at receiving and demodulating IR signals that are pulsed at its designated frequency. It includes a band-pass filter, automatic gain control (AGC), and a demodulator integrated within its design. This combination allows the module to reject a wide range of ambient light sources and potential interferences such as those from fluorescent lights and continuous IR sources, enhancing its accuracy in detecting genuine signals from remote controls.The module is encased in an epoxy package that also functions as an IR filter, optimizing its sensitivity to IR radiation while minimizing the impact of visible and ultraviolet light. It typically operates with a supply voltage range of 2.5 to 5.5 volts, accommodating a variety of power supplies and making it easy to incorporate into different electronic environments.The output from the TSOP4838 is active low and can be directly connected to a microcontroller or digital circuit for decoding and further processing. This makes the TSOP4838 a popular choice for developers creating user interfaces that involve IR-based remote control functionalities, such as in television sets, audio systems, and home automation devices. Its robust design ensures reliable performance in a compact and efficient package.
