Optical Sensors - Photo Detectors - Remote Receiver consist of four types of devices that provide similar functions and features in terms of sensing and transmitting data. They are GP1UM270XKVF, Photo Detectors, Photo Transducers, and Remote Receivers. In this article, we will be focusing on the GP1UM270XKVF Application Field and Working Principle.

GP1UM270XKVF Application Field

GP1UM270XKVF is a near-infrared medium power phototransistor ideal for voice communication systems. It is widely used for infrared remote control systems, for example, remote switches, digital still cameras, television sets, air conditioners, and TV games. Its applications range from medium power applications of up to 40mW to power for high power applications up to 100mW. Of particular note, GP1UM270XKVF can control a wide range of device from a distance of up to 15 meters in open air. Additionally, this sensor allows the operation of DC motors without a separate power source, and this makes it an ideal choice for remote control and automation applications.

GP1UM270XKVF Working Principle

GP1UM270XKVF consists of a phototransistor and is operated through an adjustable current source. The photo-detecting part of this device is a phototransistor which is based on the principle of the photodiodes. As the light intensity differs, the collector current variations. The output signal amplitude is obtained using a current amplifier in the form of a common emitter amplifier. When the current is applied to the collector of the phototransistor, the light drives the transistor into conduction, allowing current to flow. The emitter current is directly proportional to the illuminating light intensity.

The maximum limit of illumination intensity which will affect the response of this device is 40mW. The output signal is further amplified using a local amplified circuit which varies the output voltage and current, allowing control of the direction and speed of the motor.

Conclusion

In conclusion, the GP1UM270XKVF is an ideal choice for medium power applications up to 40mW and high power applications up to 100mW. It is used for infrared remote control systems and can control a wide range of devices from a distance of up to 15 meters in open air. Additionally, this sensor allows the operation of DC motors without a separate power source, and this makes it an ideal choice for remote control and automation applications. Finally, it works on the basis of a phototransistor, with the output signal being amplified using a local amplified circuit, and this results in an excellent response from remote distance.
