How to increase the power of wireless remote control

浏览次数: 2020-01-08 15 : 04 : 41Views : Times

The wireless remote control is a kind of wireless transmission installation. After modern digital coding technology, the key information is stopped coding, and the light wave is transmitted through the infrared diode. The device stops decoding and demodulates the corresponding instructions to reach the control set-top box and other devices to complete the required operation request. So how to improve the power of wireless remote control? If you want to improve the output power of the wireless remote control, you need to add a high-frequency amplifier circuit (complicated, not recommended), but this is not something that can be done at will. If you want to increase the remote control interval without increasing the circuit, you can use the following methods to debug. Add inductive coils, thin wires on the original antenna, etc. To what extent is it detailed, lengthen the transmitting antenna. Can change the appropriate small antenna. It takes experimentation. In the past, the antenna contacts were disconnected, and then the enameled wire was used to make a circle inside the remote control, and then the two ends were soldered to the antenna contacts. Just change it to 12V, and slightly improve the battery voltage of the remote control. This is easy to use with a 9V powered remote control. Adjust a small trimming capacitor inside (if any), change the transmitting frequency of the remote control, and extend the control interval.
