Jan 23, 2017

Infrared remote control and wireless remote control is for different carrier, is to use infrared ray to transmit the infrared control signal, it features a direction, there cannot be blocked, distance is generally not more than 7 meters, are not affected by electromagnetic interference, is the TV remote control infrared remote control; Radio remote control is to use radio waves to transmit control signals, its characteristic is omnidirectional, can not control, face to face distance (up to tens of meters, even several kilometers), and susceptible to electromagnetic interference. In the field of need to penetrate or non-directional control over a long distance, such as industrial control, etc., using radio remote control is easy to solve.
