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...

You want to switch on your computer as soon as you arriving home. But the computer is in the bedroom, so every time you have to go in the bedroom to turn it on after entering the door. Then you may wonder if there is an easier way to control the computer. The answer is yes. Choose wireless momentary remote control switch model of 0020002 (S1M-DC12 & C-1). Wiring operation is quite simple. Step 1, take the computer apart and find out two power switch wires. Step 2, connect two wires to normally open terminals B and C on the receiver; and connect power supply wires to terminals + and -. Step 3, solder two wires from terminals B and C to the power switch wires. Step 4, press remote button, switch on the computer.

Power strip is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket. Power strips are often used when many electrical devices are in proximity, such as for audio/video and computer systems. They are reliable, convenient and cost-effective. But you still have to press the socket switch by hand to power up and down the devices. So how about using our rf remote controller to control the power strip? We can wire the power strip to the receiver and use wireless transmitter to control it. Now let's have a try. First of all, we prepare things as follows: 1 x ac high power rf remote controller 100m 1 x power strip 3 x lamps 1 x power plug for the receiver Supposing the power strip is applied to powering 3 lamps up and down. Then we start wiring. Connect the power plug wires to the input terminal of receiver, so that it c...

James has a water level sensor to detect both low and high level of water in tank. When it detects water in low level, he will switch on the water pump. When it detects water in high level, he will switch off the water pump. Now He wonders if there is some kind of rf remote control kit to make things easier. The rf remote control kit includes remote transmitter and receiver. Supposing the remote transmitter is wired to the water level sensor and the receiver wired to the water pump motor. When the water level sensor detects low water level, the transmitter will send a signal to the receiver. After the receiver receive the signal, the water pump will be switched on automatically. Likewise, when the water level sensor detects high water level, the water pump will be switched off automatically. So he no longer has to switch water pump on and off by hand. He comes to ask us and we tell him that we have this kind of rf remote control kit . According to his requirement, we select model...
