Optical sensors use light as the sensing parameter. They detect light in broad spectral ranges from near infrared to Ultraviolet (UV) and in some cases even visible light. Photo detectors, also known as photoelectric sensors, are a type of optical sensor that convert light into electrical energy. In this article, we will discuss the application field and working principle of GP1UM291QKVF, a typical type of remote receiver which belongs to the photo detector family.

Application Field

The GP1UM291QKVF photo detector is mainly used for wireless communication purposes, providing reliable, high-speed reception for a variety of applications. It is suitable for full-duplex communication in medical devices, communication systems, home appliances, and personal computers. Additionally, the GP1UM291QKVF photo detector is an ideal choice for data receivers in Bluetooth Beacon system. In this system, it receives angle coded signals from small Bluetooth receivers, converts them into digital signals, and summarizes the information.

Working Principle

The GP1UM291QKVF photo detector uses a silicon pin photo detector to detect remote signals coming from the receiver. It has a peak working wavelength of 805nm, well suited to the infrared spectrum. The highlights of the GP1UM291QKVF two-fold working principle are signal amplification and photochemical conversion. When an electromagnetic wave in the infrared region reaches the silicon photo detector, its light generates free charge carriers inside the silicon. These free charge carriers are stored on a built-in capacitor and subsequently amplified by the integrated pre-amplifier. Finally, the signal is turned into a digital signal which is transmitted and processed further.

Conclusion

The GP1UM291QKVF remote receiver is an effective and popular photo detector which is widely used in wireless communication systems. Its application field is expanding over time, due to its proven reliability and robustness. Additionally, its twofold working principle of signal amplification and photochemical conversion enables it to produce accurate and stable digital signals which can be used for a variety of applications.
