Far-Ranging 1 Channel Remote Controls Doorbell

Someone want to install a single channel remote to control his doorbell within the range of 100m. The old 12V doorbell was broken because of the construction which cannot be repaired. Ordinary wireless doorbell cannot be used because of distance. I has an idea that a transmitter is connected to the doorbell button and relay in receiver is connected to doorbell. The only problem is the control range of remote need to reach about 100m.


We recommend the long range dc power receiver S1U-DC12-ANT2 and one button transmitter CP-1.

Working voltage range of receiver is 12V. With normally open and close terminal, the voltage of the device being controlled is AC110~240V or DC0~28V. So it can be applied in 12V doorbell. And the most significant is that it has extended external antenna which makes its control range up to 2000m (6000ft). You will be satisfied with this product.
According to your requirement, you can connect the button of the bell to the transmitter by two wires. Then connect the bell to the relay in the receiver.
Setting control mode Momentary: Connect Jumper-1.
When you press the button of the bell, RF signal will be sent out from transmitter to receiver. The receiver receives to turn on the relay, then the doorbell rings. Release the button, the doorbell stops ringing.

How to Use Motion Detector to Controls Water Trickling out from Tap

Someone is searching for a motion detector controls a solenoid valve which works in a tank for hand-washing.


He found this Mini Infrared PIR Motion Detector model of 0040101 on the internet. The module can accurately detect any moving objects within the detective range and commonly be used to detect human body movement. It has higher sensitivity and broader detective range than others. The motion sensor detector will work with the solenoid valve.

Wire the solenoid valve to the detector according to the wiring diagram.

When someone puts his hands under the tap, the PIR motion sensor detector will detect and indicate the solenoid valve installed on the tap to open. The water will trickle out from tap for hand washing. It lasts about 20 seconds. The water will stop trickling out after 20 seconds.

How to Control 4 Devices with One Transmitter Toggle Mode 1CH

I want to control 4 devices with one remote. The devices will require receivers individually and also they will be pretty far apart. So I search for any suitable product on the internet.

And the supplier said I can use one remote CV-4 to work with four S1T-DC12. However, they would like to suggest that I can order four far-ranging remote control models of 0020267 (S1T-DC12-ANT2) receivers. 4 external magnetic antennas 0020909 are respectively installed to each receiver for longer remote distance and one long range remote transmitter CV-4. Working distance can reach 500m (1500FT). They are very favorable for my pretty far apart transmitter and devices. There are four buttons on the transmitter and each button controls a receiver.


Wiring diagram is as follow:

Each device is connected to the normally open B&C terminals and supplied dc 12V power supply. And each receiver is connected to the dc 12 power supply.
Press button 1, turn on device 1; Press button 1 again, turn off device 1.
…
Press button 4, turn on device 4; Press button 4 again, turn off device 4.

Published from blogger— Traffic Lights Controlling Simulation

A man needs a remote switch that will operate 3 12V DC light circuits or outlets. He wants to control traffic lights, Circuit 1 Red Light, Circuit 2 Green Light, Circuit 3 Yellow light. When green is on, red and yellow are off; when red is on, yellow and green are off; when yellow is on, green and red are off.

We would like to recommend a 4-channel remote control kit. Remote distance is about 100 meters.

Let’s do a demonstration of this remote control.
First, we should prepare some material for this demonstration.
1×transmitter
1×receiver
1×solderless breadboard
1×red led indication light
1×yellow led indication light
1×green led indication light
some lines
DC 12V power supply

Step 1:
Connect three led indication lights to the solderless breadboard and connect them to the receiver.

Step 2:
Connect to 12 V power supply.
Step 3:
Operation
Press button 1, switch on red light and turn off other lights.

Press button 2, switch on green light and turn off other lights.

Press button 3, switch on yellow light and turn off other lights.

 

 

 

Long Distance Remote Control Works in Metal Shed House

Remote control kit was purchased by someone recently. He said that he was so happy with the items because of its good performance. What’s more, he also satisfied with fast delivery and product tracking service.
He said that it is more importantly for remote control kit is to work well even in his metal shed house. For installation of a device controlled by remote controller in his house, that customer also has tried other brands’ RF products but none of them can work as well as this supplier’s.

The receiver is high power with maximum working current of 30A. It has three working modes which are toggle mode, momentary mode and latched mode. The RF signal can pass through walls, doors, floors, trees and so on. With the external mount antenna, the receiver pairs with long range transmitter-CB-2. Remote control distance of transmitter & receiver set is up to 2000m in open field.Thanks to this external extend antenna design, it enhances RF signal’s transmitting and makes excellent performance.
The wiring is not complicated. Just do as the following picture.

Lamp or other devices should be connected to normally open terminal A&B at first. Then we wire up the receiver. Press big button on the transmitter, the lamp or other devices will on; Press small button on the transmitter, the lamp or other devices will off.

The Telecontrol of 4 Pharmacy Lighted Signs

Someone has 4 small lighted exterior signs around a pharmacy building and would like to control all four signs to go on and off by a simple RF system switch. He is wondering whether this is possible or not?

He can order 4 receivers for light control model of S1X-AC220-ANT2 and one long range remote transmitter CB-4. All lights are respectively installed to each receiver for longer remote distance.
The theoretical transmitting distance is 2000m (6000FT) in the open field. Even though in actual operation, it is hindered by trees, walls or other obstacles, or interfered by other signals. It is still enough for the exterior signs around the building.

4 lighted signs should be wired to 4 receivers’ L&N terminals individually. Wiring diagram as shown below:

Press button “A”, switch sign 1 on and off.
…
Press button “D”, switch sign 4 on and off.
