Custom Solar Water Heater And LED Projector The Infrared Remote Control uses a near-infrared light transmission remote command with a wavelength of 0.76um~1.5um. The use of near-infrared as a remote-controlled light source is because the wavelengths of the illuminating and receiving peaks of infrared emitting devices (infrared illuminating tubes) and infrared receiving devices (photodiodes, triodes, and photocells) are generally 0.8 um to 0.94 um in the near-infrared band. The spectra of the two coincide, which can be well matched, and can achieve higher transmission efficiency and higher reliability.

Since the infrared remote control does not have the ability to pass through obstacles to control the controlled object like a radio remote control, it is not necessary to design each household's infrared remote control like a radio remote control (transmitter and receiver). There must be different remote control frequencies or codes (otherwise, the wall will control or interfere with the neighbor's household appliances), so the infrared remote control of the same product can have the same remote frequency or code without the remote control signal "serial door" Case. This provides great convenience for mass production and popularization of infrared remote control in household appliances. Since infrared light is invisible light, it has little impact on the environment, and then the infrared light fluctuation wavelength is much smaller than the wavelength of the radio wave, so the infrared remote control does not affect other household appliances, and does not affect adjacent radio equipment.
