How the IR receiver head works

2023-05-24

   Dongyi is an optoelectronic company specializing in the production of infrared receivers. Dongyi infrared receiver is made of high-quality materials, with stable performance and long service life. Whether it's tested in the factory or in the warehouse, the desired results are achieved. We provide support and help, so that customers can use our products with confidence, but also to ensure the reliability of quality, under the premise of ensuring quality and safety, Dongyi can provide customers with a large number of choices, so that your products are more competitive. But how does the receiver work? Now for you. The basic principle of the operation of the receiver is that we know that the visible light that the human eye can see is arranged in order of wavelength from long to short, in order of red, orange, yellow, green, cyan, blue, and violet. The wavelength range of red light is 0.62~0.76 mu. m; The wavelength range of violet light is 0.38~0.46 mu. m。 Light that is shorter than the wavelength of violet light is called ultraviolet light, and light that is longer than the wavelength of red light is called infrared. Infrared remote control is the use of a wavelength of 0.76~1.5 mu; m between the near-infrared rays to transmit the control signal. Using infrared as the operating principle of the receiving head, it can quickly and accurately sense distant objects and convert them into electrical signals. These signals can be transmitted to devices such as computers or mobile phones for various operations and data processing.

   The working principle of the infrared receiver can be further subdivided into the following steps: Infrared signal reception: The infrared receiver first receives the infrared signal from the infrared emitter through its infrared sensitive element. Signal Conversion: The received infrared signal is converted into an electrical signal, which is done by an infrared sensitive element. Signal Processing: The electrical signal is then processed by amplifiers, limiters, and filters to remove noise and interference and improve the quality of the signal. Decoding: The processed electrical signal is decoded by the decoder into a corresponding digital electrical signal, which is key because it converts the analog infrared signal into a digital command that the device can understand. Output control signal: The decoded digital electrical signal is output to the controlled device to trigger the corresponding operation. Dongyi infrared receiver is widely used in LCD TV/air conditioner/lighting/projector/electronic candle/audio/fan/network set-top box/smart toilet/smart water and electricity meter/remote control toys and other products
