water pump – Remote Control Everything

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.

1 Channel Mult-Modes Remote Switch for Float Switch and Pump

Question from customer:

A relay is activated by a float switch through 600 feet of underground wire (12 volt dc) to control a water pump. But this wire was broken. So controlling between float switch and relay is cut off. I need a transmitter activated by float switch, and a receiver which activates a 12 volt relay. I have 12 volt power supply for receiver and transmitter.

Answer:

We recommend the normally open/ closed remote control applied for device control another device (S1PU-DC12-ANT2 & CB-2N).

The transmitter, CB-2N, is battery-operated long range transmitter with extended two wires. Triggered method of this transmitter is connection of two wires. When two wires are closed, the transmitter will send signal to receiver. The receiver is high power with normally open and closed terminals. With extended antenna, the theoretical working distance of remote controller is up to 2000M. Now that the wire between float switch and relay was broken, you can connect your float switch to two wires of CB-2N, and use this receiver S1PU-DC12-ANT2to replace your 12 volt relay. Please see the following picture.

Normally open and closed terminals A&B are connected to water pump. And we supply power source to receiver.

When the tank is empty, the float switch circuit is closed to trigger transmitter (CB-2N) to send signal to receiver. When receiver receives “ON” signal, it will activate pump to fill water into tank. When the tank is full, the float switch circuit is open to open transmitter circuit to send signal to receiver. When receiver receives “OFF” signal, it will stop pump to pump water to tank.

Remote Control Pump Instantly

Question from customer:

I want to remote control a water pump in the upstairs garden on and off from my kitchen which requires a momentary start signal. The pump has its own power from 110/120V AC and timed operation. Would you like to recommend me any favorable remote control switches?

Answer:

We recommend you 1 channel AC remote control (S1M-AC220+C-1). This 1 channel RF wireless remote control switch system is triggered by AC power (100V~240V)and allows you to control your lights, garage doors, fans, motors, cars…within about 100 meters distance. The receiver is direct power output. Power supply for the receiver and the water pump are the same. It means that you don’t have to prepare another power supply for water pump operation.

Wiring program is as follow:

Wire water pump to the zero wire and live wire (terminals 3&4). Then supply 100V~240V to the receiver.

Operation:

Press button and hold: Turn on relay, terminals 3 and 4 output AC power. The water pump can be activated.

Release button: Turn off relay, terminals 3 and 4 no output. The water pump will stop working.

Pumping water automatically with remote control system

James starts to manage a farm since this year. He needs to pump water to tank in the water tower for irrigation every day. At the beginning, James installed a water level sensor which is connected a gadget with two indication lights. When red light flashing, it means that the water level is low. He needs to switch on the water pump by hand. When the green light flashing, it means that the water level reaches the high level. Gradually, it is tired of him to run to 1000m away to monitor whether water level in the tank gets low or high and switch on or off the pump motor every day. So James would like something will send signal which can make switch of the motor turn on to pump water automatically. So how can we combine pump motor and water level senor with remote controller? Recently, we promote a latched rf remote control system,With the combination of those two gadgets, using a water level senor to remotely control the water pump motor is no longer a Gordian knot. This is a long distance remote controller kit. Transmitting distance is up to 1000m in open field.

In addition, the major characteristic of CB-2N is that it has two extended wires, which is wired to the electric device. When two wires are connected, the rf signal ”ON” will be sent out; When two wires are disconnected, the rf signal “OFF” will be sent out. That is easy to operate.

First, look at the circuit configuration.

Here is the wiring picture. The extended wires on transmitter should be connected to the water level sensor. The red wire from the motor is connected to the C terminal of the receiver and black wire from the motor 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 the water level gets low, it makes the contacts of water sensor are closed; with extended wires of transmitter connection, the transmitter is triggered and transmits an RF signal “ON” to the receiver. The receiver output contacts are closed after received the signal, the pump begins to pump water. When the water gets high, it makes the contacts of water sensor are cut; the transmitter is triggered and transmits an RF signal “OFF” to the receiver. The receiver output contacts are cut after received the signal, the pump stops pumping water.

RF Momentary Remote Activate Hot Water Pump

One of our customer said that he’d like to activate a hot water circulating pump in the upstairs bathroom from his kitchen which required a momentary start signal. The pump had its own power from 110/120V AC and timed operation.

We recommend 1 Channel DC RF Momentary Remote Transmitter Receiver (S1M-DC12 & C-1) to him. 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.

Simple wiring image is as follow:

Press and hold the remote button, he can activate the hot water circulating pump.
