DIY Automatic Irrigation Pump

Question from customer:

I need to start and stop an electric motor (water pump) 1500 meters away from a house. The water pump is initiated by an irrigation controller. A relay n/o or n/c contact is automatically operated from the irrigation controller when no one is home. Currently there are 2 wires running all the way and are regularly damaged by cows, fires, machinery. I wish to start and stop this motor via remote control, but there are no always people there to push the button on a remote control. This start is initiated by a voltage free relay contact.

Answer:

We recommend the 1 channel high power long range receiver S1PU-AC220-ANT2 and 5~28V triggered transmitter CB-2V.

The outstanding feature of this transmitter is that it has two wires, when two wires connect to low voltage, transmitter will send signal to receiver to activate controlled appliance.

The receiver is 1 channel with extended antenna and multiple working modes. When it pairs with its transmitter, its transmitting distance is up to 2000M in the open air.

Here is the wiring diagram for transmitter and receiver.

For transmitter, you can manage to find an electric device as a triggered switch for its two wires. Do as following shown, connect two wires to electric device.

For the receiver, there are normally open/ closed terminals. Usually, we wire electric device to the normally open terminals. So A&B terminals are normally open; A&C terminals are normally closed. We can connect motor to A&B terminals. And connect a wire between B&L terminals and another wire to A&N terminals. Through N&L terminals, supply AC power to the receiver.

When the transmitter is triggered by low voltage to two wires, it will transmit “ON” signal to receiver to open the irrigation pump. When power is cut off, it will transmit “OFF” signal to receiver to stop the irrigation pump.

Manual Switch Turn on LED On the Receiver Remotely and Turn off it after delay time

Question from customer:

The transmitter is to function as a switch to the receiver activated by supplying a 12v DC

current to the transmitter (switching it on).

The receiver then permits a 12v DC current to be supplied to a specific appliance. When the transmitter is shut off the receiver should have a 15 to 20 second delay before stopping supply to its appliance which will then shut down.

Answer:

We recommend this kind of controlling unit —12V time delayed receiver and low voltage triggered transmitter (S1X-DC12-ANT2+CB-2V) to you. It is applied for device controlling another device. The remarkable characteristic of the transmitter CB-2V will be triggered by DC power 5~28V input. That’s to say, when you give voltage of 5~28V to the transmitter, transmitter will be on. We add external extended antenna which makes transmitting distance up to 2000m. We design time delayed function program for this receiver which can realize that the controlled appliance on the receiver will be off after 15~20 seconds when you shut off transmitter. We can preset time according to you requirement.

According to the picture above, he wants the transmitter can be activated by manual switch and turn receiver on/off when the current in that circuit is on/off. First, the transmitter is supposed to be connected to power supply and that manual switch. Second, designated appliance should be connected to receiver. In addition, you don’t have to supply power to your appliance because appliance will get power through powered receiver.

Let’s see practical use. Here is the transmitter and manual switch wiring.

We switch on the manual switch and the transmitter will send an “ON” signal to the receiver. The receiver receives the signal to instruct the light to turn on. We switch off the manual switch and the transmitter will send an “OFF” signal to the receiver. Owning to the time delayed program, the receiver won’t give response to transmitter. After 15~20 seconds, the receiver will instruct the light to turn off. (The delay time is preset according to your requirement.)

Alarm Siren Remote Controlling by Triggered Transmitter and 1 Channel DC Receiver 2000M

Question from customer:

I am searching for a solution to send a wireless signal across roughly 300m. The receiver will be 12v powered. The transmitter will be used turn on with a relay then send a wireless signal to the receiver. The receiver in turn will activate a 12v alarm siren system. These need to be sending while in alarm and stop sending when the relay shuts off.

Answer:

Our suggestion is 2000M RF remote control apply for device control another device (S1L-DC12-ANT2+CB-2N).

The remarkable feature of its transmitter is that its triggering method is connection and disconnection of two wires (Black&Red).

This transmitter & receiver set can be used in such a situation when you want to use an electrical device to remotely control another device. It has extensive application range. It controls lights, motors, fans, electrically operated doors/locks/windows/blinds/cars or other appliances with voltage AC110~240V or DC0~28V. You can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance (within 2000M open field); the wireless RF signal can pass through walls, floors and doors.

You may wonder how it works with alarm sirensystem. Let’s see the following wiring and operation procedure.

Wiring:

Wires on the transmitter should be connected to the contacts of original device. Here we suggest that you can add a manual switch between two wires to control its connection.

The normally open contacts B&C of receiver should be connected to the alarm siren being controlled. We offer three voltage versions for receiver: 9V, 12V and 24V. You can choose the right one according to the voltage of device being controlled. You can supply 12V power to receiver and your alarm siren system respectively.

Operation:

As you requirement, we finished all procedure. Move to “ON” position of transmitter’s switch. Then we move manual switch to “ON” position, the contacts of two wires are closed, the transmitter is triggered and then transmits an rf signal “ON” to the receiver. After the receiver receives the signal, contacts B&C are closed; Your alarm siren start to work.

Then we move manual switch to “OFF” position, the contacts of two wires are cut, the transmitter is triggered and then transmits an rf signal “OFF” to the receiver. After the receiver receives the signal, contacts B&C are cut; your alarm siren system stops working.

2000m DC ON/OFF Switch Remote Control Motor

Question from Customer:

I seek a transmitter-receiver 12V to run a small motor away from 300~500 meters with operating on off.

Answer:

Our suggestion is this 1 channel 12V voltage output remote control gadget (S1X-DC12-ANT2 & CB-2). Single channel is for one device. 12V direct power output can supply power directly to the device which is controlled. User can turn on/off the receiver with transmitter (remote control) from any place within a reliable distance; the wireless RF signal can pass through walls, floors and doors. The receiver, which mounts long range magnetic antenna, pairs with long distance transmitter to reach to 2000m in the open field.

There are 3 control modes. They are Toggle, momentary and latched.

Setting control mode Toggle: Only connect Jumper-2.

1) Press big button: Turn on the relay.

Press big button again: Turn off the relay.

2) Setting control mode Momentary: Only connect Jumper-1.

Press and hold big button: Turn on the relay.

Release big button: Turn off the relay.

3) Setting control mode Latched: Do not connect Jumper-1 and Jumper-2.

Press big button: Turn on the relay.

Press small button: Turn off the relay.

As regards controlling motor on and off, we suggest the latched mode. Latched mode is really favorable for long range controlling because big button on transmitter is for ON, small button is for OFF. If you want to turn on motor, you can press big more for many times to make sure that the motor is on. If you want to turn off motor, you can press small more for many times to make sure that the motor is off.

For the wiring, it is so simple. The following picture shows. Motor is connected to terminals A&B on the receiver. The receiver should be supplied 12V power. There is no need to supply power to motor because motor can get power from the receiver.

Turn on Hot Water Circulator and Make it off Automatically

Question from customer:

I want to use one device to turn on a hot-water circulator in my home for 15 minutes&then have it automatically turn off. I live in a 2 story wood home&the hot-water circulator is in the basement-maybe a distance of about 30 ft away through drywall&wood flooring. Will it work over this distance? Would I need to order a telescopic antenna?

Answer:

We think this product may be suitable for you– 1 channel ac delayed remote unit (0020483 S1DA-AC220-ANT2+CB-2). This kind of remote unit is with time delay timer, which you can adjust time according to your requirement. With external extend magnetic antenna, working distance of transmitter and receiver will reach 2000m/6000ft (theoretically).So you don’t have to order telescopic antenna.

Wiring program is as follow:

We connect delayed remote unit to circulator pump. The receiver is relay output (normally open and normally closed). Power supply for the receiver and the water pump are different. That means it will not cause electromagnetic interference during water pump operation.

Operation:

Press big button: Turn on relay (connect B and C, disconnect A and B). After delay time: Turn off relay by itself (disconnect B and C, connect A and B). Press small button: Turn off relay immediately, no need to wait for delay time.

Press buttons of “＋” and “－” on the timer, adjust delay time from 0 second to 99 hours. “H” is Hour, “M” is Minute, and “S” is Second. As your requirement, you can set “M 1 5”, it means the delay time is 15 minutes. After working for 15 minutes, it will be off automatically. Then the circulator pump stops pumping.
