radio remote control module is the use of radio signals on the remote control of the various agencies remote control device. these signals are distant absorption absorption device can command or drive machinery may be appropriate in other electronic equipment, to complete the various operations, such as a closed circuit, move the handle, motor running, and then be required by the operation of these machines. as a supplement with infrared remote control with remote control species in the garage door, electric gate, automatic barrier remote control, burglar alarm, industrial control and wireless smart home has been widely utilized. wall switch
remote control switch remote control system commonly used in emission and absorption generally divided in two parts.
absorb some general also divided into two types, i.e. superheterodyne method and the super-regenerative absorption, the super-regenerative circuit is also known as super-regenerative detector demodulation circuit, which is actually working in the state of the reproduction intermittent oscillation detection circuit. superheterodyne superheterodyne radio demodulation circuit similar, which is provided with a local oscillation circuit generates an oscillation signal, and absorbed into the carrier signal after the mixer, to obtain an intermediate frequency (typically 465khz) signal, the if amplification and detection, the demodulation of the data signal. because the carrier frequency is fixed, so some of the circuit than the radio briefly. superheterodyne absorber stable, sensitive and high anti-interference ability is relatively good; super-regenerative absorption are small, the price is cheap. switches and sockets
emitting portion is generally divided into two types, namely remote control and transmitter module, remote control and remote control module is on the way for the use of the remote control can be used independently as a whole, foreign pinout for wiring trailer coupling; rather remote modules in the circuit when a component to use, according to the pin definitions for use, the use of remote control module and use the advantage of the circuit can be seamless convergence, small size, low price, the best use, but the use of those who truly understand the circuitry necessary principle, or otherwise use the remote control to the convenience.
