How to control the loudspeaker plugged into a car on and off by rf remote controller

My dad would like to plug a loudspeaker into the trunk of his car and wanted to control it by remote controller. He was wondering if it could come true because he wanted to use loudspeaker to listen to music when he went out for picnic with us. He just searched from the internet, then he chose Model 0020003(S1L-DC12 & C-2) from one remote control supplier.

It is the wiring procedure which the supplier shows to him. The red wire from the loudspeaker is connected to the C terminal of the receiver and black wire from the loudspeaker is connected to the negative electrode of the power supply. The positive wire of the supply power is connected to B terminal and positive electrode of the receiver. The negative electrode of the power supply of power supply and receiver are connected together.
When we press the button1, the loudspeaker turn on; when we press the button 2, the loudspeaker turn off.

How does the mercury switch remote control the garbage bin

I  have a mercury switch and I  intends to apply to my garbage bin. So when the truck tips garbage bin, I can know it in time. Now I am looking for a remote control kit which can connect to mercury switch to attach that garbage bin. When the garbage bin is tipped by the truck, the mercury switch is on and triggers the remote controller to turn on the light in the house. So I select this control kit which are model 0020259 S1DA-AC220 & model 0021000 C-1. S1DA-AC220 is a receiver with a timer. C-1 is the transmitter.

First, the mercury switch is supposed to be soldered to those two terminals of button.(see the following picture)

Second, this unit should be attached to the garbage bin.
Third, the power supply should be connected to the N&L terminal of the receiver.
Wires from the light should be connected to B&N terminal of the receiver. Then we use another wire connect to C&L terminal of the receiver.

We press buttons of “＋” and “－” on the timer to adjust delay time. I set 5 minutes for this timer.

When the truck comes and picks up the garbage bin, the garbage bin will be turned upside down so that the mercury will roll to another side. With connection of two wires at another side through mercury, the transmitter will send signal to receiver. After the receiver receives the signal, the light will shine and last for 5 minutes. Then the light will turn off automatically after 5 minutes. With shining of light, we know that the garbage truck tips garbage into truck and takes away. 

1 Remote Transmitters & 6 RF Receiver used for opening or closing 6 awnings

My aunt manages a sidewalk cafe. When the dazzling and hot sun shining or drizzling day and shower coming, awnings should be opened for her customers. So she needs a remote controller to control those 6 awnings without going everywhere.

She selected this remote control kit.

She wants this kit to be like this:

She said to me that each of the receivers should learn code from the transmitter so that every two buttons on the transmitter can control each receiver.

Each motor of the awning should be connected to the receiver one by one. Every receiver should be connected to the power supply.

When she presses button 1, with the motors of awning 1 working continuously in “UP” direction, awning 1 goes up slowly. Release button 1, the motor stops. Press button 2, the motors of awning 1 goes to “Down” direction. When pressing and releasing button 3& button 4, we can control awning 2…When pressing and releasing button 11&button 12, she can control awning 6. My aunt is very satisfied with those remote control kit.

How do you know when the truck tips your garbage bin outdoor with RF vibration detector

I just want to use wireless remote controller to attach his garbage bin outside. When the truck picks up the bin and tips garbage, the controller will detects and turns up a light in the house. So I can know that the garbage is taken away. It sounds a very innovative idea. I have no idea to realize it?So I searched on the internet and asked a remote control supplier, they select a remote control kit for me. That is model 0020259 & model 0010032 (S1DA-AC220 & W-12). They are the remote control kit with functions of vibration reminder and time delay.

They told me that W-12 is an RF vibration detector. When the item is vibrated, the vibration detector will be triggered and will send signal to the receiver to instruct the device to work. S1DA-AC220 is a receiver with a timer.

It looks like great.

With the procedure they shown,  I stick the detector to the garbage bin and pull out the antenna. (To see the following picture)

Then I begin to wire. The power supply should be connected to the N&L terminal of the receiver. Wires from the light should be connected to B&N terminal of the receiver. Then I  use another wire connect to C&L terminal of the receiver. (Wire as the wiring picture they show me)

The operation time came,  I press buttons of “＋” and “－” on the timer to adjust delay time. I set 5 minutes for this timer.

When the truck comes and picks up the garbage bin, the garbage bin is vibrated so that the vibration detector is triggered and the light will shine and last for 5 minutes. Then the light will turn off automatically after 5 minutes. With shining of light, I know that the garbage truck tips garbage into truck and takes away. I like this little , useful, handy gadget.
