What is the principle of home appliances remote control?
Most commonly used remote control infrared technology, infrared, also known as infrared light, which belongs to a kind of invisible light. Infrared light by wavelength range is divided into near infrared, mid infrared, far infrared, infrared 4, infrared remote control is the use of near infrared remote control command, the wavelength of 0.76 microns to 1.5 microns between.
Solar spectrum
A near infrared remote control as the light source, because the infrared emitter and infrared receiving device and light luminescence wavelength of 0.8 microns to 0.94 microns, just in the near infrared band, spectral overlap of the two, can be a good match, the reliability can be obtained and the higher transmission efficiency.
The principle of infrared remote control infrared remote control is relatively simple, through the light emitting diode to send out signals for invisible infrared, infrared and home appliances in front of the receiver and then turn into a signal, then the signal can control the home appliances.

Since the infrared remote control device was introduced in 80s, it has been used in most household appliances because of its low cost and easy to use. However, the shortcomings of infrared remote control is also obvious, that is, must be a straight line point to point remote control, and short transmission distance, remote control and electrical appliances can not be a barrier.
Bluetooth remote control
Now some manufacturers have begun to abandon the infrared, the use of Bluetooth remote control output, such as millet TV and some TV boxes are using a Bluetooth connection. At the same time, there are a lot of smart TV supports WiFi remote control function, using direct WiFi technology, can make the intelligent mobile phone in the same WiFi under the direct control of household appliances.
However, the infrared remote control is still the mainstream, and in the appliance industry is widely used, can not be replaced in a short time. Therefore, there are many manufacturers launched a built-in infrared transmitter phone products, with the relevant APP, so that the phone can easily manipulate a variety of home appliances.
Mobile phones can also remote control appliances?
In fact, equipped with infrared interface is not what new things in the mobile phone, as early as the age feature phone a few years ago, there was a lot of mobile phone is equipped with an infrared transmitter, because the Bluetooth technology is not universal, is mainly used in mobile phone interface infrared data transmission distance, of course, Windows Mobile mobile phone can also be install software to realize remote control function. Later, after the popularity of Bluetooth technology, there is little mobile phone and then equipped with infrared interface.

This year, there are a lot of new smart phones began to be equipped with infrared interface. For example, Samsung's S5 GALAXY, as well as millet phone 4 and other products, these phones have an infrared transmitter, with the phone's built-in remote control applications, can be adapted to almost all the mainstream of home appliances.
Which phone can be used as infrared remote device?
What about other mobile phones?
However, if your phone does not have a built-in infrared transmitter, it does not matter. After all, the built-in infrared transmitter phone products or a small number, for most ordinary smart phones, there is a solution, that is, Taobao.
Universal remote controller for mobile phone
There is a kind of mobile phone accessories called "mobile phone universal remote control", by inserting the headset interface, realize the infrared remote control, and this kind of accessories price basically in less than 50 dollars, the accessories can support most of the Android mobile phone and iPhone.
