Working Principle

GP1UM271XKVF works on the principle of photoelectric effect. It consists of a photodiode and a phototransistor. When the infrared ray from the environment is received by the photodiode, it will emit electrons and turn into current signal which will be amplified by the transistors connected within the phototransistor. The signal is then output.The inner circuits of phototransistor have a wide range of voltage amplification. It can receiving the infrared ray even in a poor illuminating environment, and amplifying the signal to the level of noise ratio. This signal can be detected by the micro-controller. The GP1UM271XKVF has excellent environmental adaptability due to its one-chip design. It can operate under various temperatures and humidity such as high temperature environment. The signal generated is stable and the linearity of the infrared signal received is high. It minimizes the effect of ambient temperature or humidity on the signal delivered and makes sure that the output signal is accurate.

Conclusion

GP1UM271XKVF is an advanced and widely used photodiode for remote receiver application. It is used in anti-counterfeiting system, wireless system, remote control systems, and production line control and other industries. It works on the principle of photoelectric effect and performs comprehensive functions such as amplifying circuit, voltage amplification circuit and excellent environmental adaptability. It is capable of receiving low level of infrared ray and has high linearity and stability.
