RF Remote Control Blog

One of our customers wants a simple wireless remote operate 4 led lamps from several room at his house. He needs 4 transmitters and a receiver which can be mounted in a designated place. The remote must work from receiver about 50m away and not line of sight through doors and walls. We suggest him choose dc 4 channel remote control system  (S4C-DC12& 4C-1). Maximum working current is 5amp each relay. Working distance of remote and receiver set is about 100m (300ft) in open field. This 4CH 6V9V/12V/24V wireless remote switch operates in toggle, momentary, latched, toggle + momentary control mode (set the mode as you like freely). Easy to install and operate. Just press slightly the button on the remote, you can control universal DC/AC electrical devices. The RF signal can pass through walls, doors and other barriers. As he said, we will set 4 transmitters and this receiver with same 8-bits code in advance so that they can work together. Operation modes: 1) Setting control ...

One customer said he would like to install 6V led lamp into the trunk of his car and wants to control it by remote controller. He is wondering if it can come true because he wants to use LED lamp to illuminate with use of 6V battery. We recommend him 1 channel 6V latched remote control kit (S1L-DC06+C-2). This kind of remote control kit is activated by 6V power supply. So he doesn’t have to supply additional power for led lamp because led lamp will get power from powered receiver as long as you wire lamp to the receiver. With latched mode, he can press button 1 of transmitter to turn on led lamp and press button 2 of transmitter to turn off led lamp. If he wants to set on / off function respectively, it is better choice. It has normally open and closed contact. It controls various lights, fans or motors with voltage AC110~240V or DC0~28V. Of course, if he wants to remote control alternate current device, he needs to do some different wiring from direct current device. Here is the ...

We will try to make motion detector led lamp with infrared motion detector (W-01) and rf receiver with time delay function (S1DA-DC12). The working distance of motion detector is 100m (open field). The detection distance is 10m. The rf receiver is an adjustable time delay receiver. Delay time can be adjusted as you like within 0 second~99 hours.   Online shop:  http://www.carymart.com/

This rf remote control transmitter & receiver 0020521 (S1XL-DC12-ANT2 & CB-2V) can be used in such a situation when you want to use an electrical device to remotely control another device. It features in long distance and direct power output functions. Remote distance is 2000m (in open field). The input and output power are the same as DC 12V. Easy to wire and operate.  Next we will explain how it works in detail. We take one led lamp as the original device, the other one as the device being controlled. The transmitter has two extended wires. They are connected to the original led lamp to send out rf signal. The receiver is for receiving the signal. The led lamp being controlled is connected to the receiver. When the original led lamp is on, the led lamp being controlled will be switched on automatically. Firstly, choose one led lamp to be the original device. Solder the red wire on transmitter to the output terminal “+” of the lamp and the black wire to th...
