How the IR Receiver 38 kHz Remote Infrared Module TSOP4838 DIP-3 works ?

1. Detection of Infrared Signals: The TSOP4838 DIP-3 module contains an infrared-sensitive semiconductor that is specifically tuned to detect signals at a carrier frequency of 38 kHz. When an infrared signal is transmitted towards the module, it is absorbed by the semiconductor material.

2. Signal Demodulation: The infrared signal received by the module is modulated at a specific carrier frequency (38 kHz in this case) to encode information. The TSOP4838 DIP-3 is designed to demodulate the incoming signal, separating the carrier frequency from the data signal.

3. Output Signal Generation: Once the infrared signal is demodulated, the TSOP4838 DIP-3 generates a corresponding electrical signal as output. This electrical signal represents the detected infrared data and can be further processed by the connected electronic device.

4. Amplification and Filtering: The output signal may undergo amplification and filtering within the module to improve its quality and reliability. This ensures that the electrical signal accurately represents the original infrared data received by the module.

5. Output to Electronic Device: The processed electrical signal is then transmitted to the electronic device to which the TSOP4838 DIP-3 module is connected. The device can interpret the received signal and perform the appropriate actions based on the transmitted data.
