Movement Detector And Time Delay Receiver For Water Feature Pump Motor

Question from customer:

“I have a waterfall water feature that currently has an 110v 250W pump that run from 7AM until 10PM. I would like to save more energy by having these pumps turn on by detecting motion near the water feature. 110 degree detection, within 30 feet would be sufficient. The more intelligent, the better (i.e. body/heat/motion/mass detection). There is no need to run a waterfall water feature when no one is there to enjoy it. What do you recommend?”

We recommend wireless infrared movement detector and receiver with time delay function (S1DA-AC220-ANT2&W-01) to you. This kit is 220V actuated. With external extended antenna, it can work within 6000ft in the open field. With adjustable time delay function, you can adjust delay time from 0 second to 99 hours. The motion detector can detect any movement within 10m. Detection range is fan-shaped angle 110°.

We’d like show you how to use this kit.


1 Using screws to fix the bracket on the wall to favorable locations according to your need (i.e. the corridor towards waterfall water feature) and put the detector on the bracket, then adjust the detector to the suitable angle of 10~14° and turn on it.

2 Wire pump motor to B terminals of receiver (A, B = Normally Closed; B, C = Normally Open). Press buttons of “+” and “-” on the timer of receiver, “H” is Hour, “M” is Minute, and “S” is Second. We suggest you that you can set your pump work every 30 minutes from 7AM to 10PM. Once people pass corridor towards waterfall water feature, the motion detector is triggered. You can set “M30”. And supply power to receiver and pump motor.

3 When the movement detector is triggered: Turn on relay (connect B and C, disconnect A and B).

The pump motor begins to work. It will last 30 minutes if you set “M30”. After delay time, there is no motions any more, it will turn off by itself.

Question from customer:

“I would like to control my hot water recirculation pump via remote control with time delay. I would like one receiver unit that can provide 4 different time delays (i.e. #1 1 minute, #2 2 minutes, #3 for 3 minutes, #4 for 4 minutes) via 4 different transmitters. Do you have such a product?”


We think that you may need two time adjustable ac receivers and a 4-button transmitter (S2DA-AC220&C-4). The receiver is relay output (normally open and normally closed). Power supply for the receiver and the water pump are different. They can turn off automatically after the delay time(0 seconds ~ 99 hours), this RF wireless remote control switch system should be a good choice for you to control your all kinds of DC 0-28V or AC110 ~ 240V electrical appliances at home!

You can wire 4 pumps to 4 different relays of two receivers respectively.




Press buttons of “+” and “-” on the timer from two receivers, adjust delay time from 0 second to 99 hours. Two buttons of Timer 1 adjust delay time of relay 1; two buttons of Timer 2 adjust delay time of relay 2. “H” is Hour, “M” is Minute, and “S” is Second. For example, if you set “1 0 M 0 3” on Timer, it means the delay time on Timer 1 is 3 minutes; the delay time on Timer 2 is 10 minutes.

Set relay 1 for 1 minute; relay 2 for 2 minutes; relay 3 for 3 minutes; relay 4 for 4 minutes.

So for the first receiver, you can set “02M01”; for the second receiver, you can set “04M03”.

And press button 1 turn on, pump 1.

Press button 2 turn on, pump 2.

Press button 3 turn on, pump 3.

Press button 4 turn on, pump 4.

After preset delay time, they will turn off automatically. If you want to turn off pump immediately, you can press button again for each pump to turn off them at once.
