Today little X teaches you to use your smartphone to do a universal remote need to prepare some materials: 1: An infrared emitter with 38K carrier, (wavelength 940nm) Standard mode: 30khz~60khz; Remote mode: 38K.Our universal remote control best Use brand brand 38k+-5kb are applicable to the normal 38k+-3kb applicable part of the remote control carrier maximum to the maximum 38k±20k, our remote control will not be used, so our universal remote control

Coding/decoding and recognition driver for infrared remote control Because the encoding formats of different remote control may be different, here is only the single-chip computer recognition program of this remote control I currently use and the method that can decode the infrared remote control with unknown encoding formats. The infrared remote control code is

Article title: ZK-ID6USB infrared has been successfully used in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Compared with the infrared transmitters integrated in the notebooks of major manufacturers, this independent USB port transmitter is difficult to drive

I have been using UbuntuFeistyFawn for a long time. The infrared lights in this book flash every few seconds and scan the infrared devices around me. I don't have any infrared devices, so I'm depressed. It's useless. I searched the internet for a long time. Only how to enable infrared in Linux --! Today I have studied

Many home appliances are used infrared remote control, such as TV, set-top box, air conditioning, electric fans. More and more remote control has brought us more problems, sometimes can not find where the remote control, or confusion is the trouble, in fact, the simple transformation of the mobile phone, it is possible to homemade a universal infrared remote control, to see how we "control" home appliances.

　　Huaqing Vision LecturerWe know that embedded learning human eyes can see the visible light by wavelength from long to short arrangement, in turn, red, orange, yellow, green, green, blue, purple. The wavelength range of the red light is 0.62~0.76μm; The violet wavelength range is 0.38~0.46μm. The light that is shorter than the violet wavelength is called ultraviolet light, which is longer than the red wavelength is called infrared ray, see Figure 1.

Abstract:The development of the signal processing circuit of the infrared focal plane array is introduced. The basic structure, working mode and application fields of CCD Multi-Channel transmitter (CCD-MUX), time delay integrated CCD (TDI-CCD), MOS and CMOS multi-channel transmitter (CMOS-MUX) are described. Finally, two application circuits of multichannel transmission devices are provided. Keywords:Signal processing circuit of

Modern security monitoring is increasingly being valued. It is generally composed of image acquisition, transmission and storage system. The use of high-precision cameras with advanced image processing technology and transmission technology. Although its security monitoring performance is very good, but there are large investment costs, real-time alarm performance is poor. Large amount of data, the shortcomings of concealment. In view of these shortcomings, some applications can also use

The application background of infrared video moving target detection: the usual video target detection, often is the visible light target detection, this detection and tracking technology has been very mature, but there is an unavoidable flaw, it is not in the light of the situation to carry out effective detection, in the night without light can not be detected at all. and infrared detection can make up fo

I recently found a post about infrared photography hanging out on the Internet, which is very good: Link: http://vip.6to23.com/irphoto/index.php/www/content/view/full/56/56.htmlTwo methods for taking infrared photos with a Sony 707 or 717 digital camera Because Sony 707 and 717 have strong infrared capabilities, there are two ways. Here is a brief introduction. T
