GP1UM287QK

Optical sensors are used to detect objects or measure distances by reflecting a light beam off of a reduced reflecting surface. Photo Detectors, such as the GP1UM287QK, are used to convert light from a light-emitting diode (LED) or other optical source into electrical signals. The Remote Receiver, in this case the GP1UM287QK, receives the light which is sent in an infrared (IR) light range and converts it into electrical signals. The GP1UM287QK works in two separate areas: it senses range and intensifies the received light.

The GP1UM287QK has an operating range of up to 4 m and can be used in robotics applications. This is because of the fact that the GP1UM287QK can receive reflected faint light of an LED or other sources, and then amplify them into a readable electrical signal.

The working principle of the GP1UM287QK is based on a light emitting diode which emits infrared light to the reflector, and after this the receiver will receive the corresponding signal which is transmitted back. This is done in such a way, that only when the reflected signal is received from the target, will the receiver activate to detect it. This basically means that the receiver has to receive twice, once when the emitter is sending out the signal and one when it is receiving the reflected signal.

The working principle of the GP1UM287QK is very simple, but at the same time quite efficient. Once the light beam is sent out, upon its return it is amplified by the analog amplifier. Then the digital signal is filtered with a peak filter and then transmitted to the address bus. This returns a digital signal which can be further processed by the microcontroller.

When measuring the distances, the GP1UM287QK can determine the time of flight of the light beam since its LED is continuously emitting the infrared light. The flight time is obtained by measuring the pulse width of the digital signal output, which is proportional to the time it took for the light to travel from the emitter to the receiver. This information is then further filtered with a median filter for smoothing the errant readings. Finally, the distance is calculated by dividing the pulse width by the velocity of the light.

The GP1UM287QK is capable of working at temperatures of -25°C to +80°C and can work even under atmospheric pressure. It is designed to protect against short circuit and reverse voltage, as well as high-intensity light, which makes it very stable and easy to use.

Overall, the GP1UM287QK can be used in a wide range of applications, such as robot navigation, indoor positioning, factory automation, medical equipment and more. It has a long operating range and can withstand atmospheric conditions, making it ideal for large-scale projects requiring non-contact distance sensing. The GP1UM287QK is also simple and cost-effective, making it a great choice for any application requiring accurate distance measuring.
