I need help from this community. I'm novice user. My house is in low land. It fills out during rain and we have hard time always to pump out those collected water with our regular 220 V water pumps. Can any of you suggest a circuit that i can assemble for:
1. Sense water deposition and start pump automatically.
2. Once water get pumped/or say level goes low enough stops the motor automatically.
I would appreciate of your help for a simple circuit that i can buy components and assemble them. Please no with Arduino or something like that. Real simple that works without programming. Please!
Many submersible have a float switch attached which start and stop them automatically. This is one example. You will also find many float switches on ebay but some will not be capable of switching the power to the pump directly. These would require the use of a relay and possibly a low voltage power supply depending on the contact rating of the switch.
I second the float switch idea. Depending on how much current the pump draws, you may have read to use the float switch to switch a relay, and the relay switch the pump.
Float switches come in many types – one of the easiest to use might be a bilge pump switch.... a relay would almost certainly be required in this case.
Likewise, float switch - it's an absolutely standard device for a pump, and many pumps come with them ready fitted.
Funnily enough, I repaired one at work the other year - the float switch had failed, and we got a replacement and changed it.
Been a nosey type I cut the old one apart, to find it was simply a large ball bearing that rolled about and pressed on a micro-switch. I kept the ball bearing, it was too cool to throw away
Further to what everyone has already said, the normal way to use a submersible pump with a float switch is to dig a "sump" for it to sit in. The sump is a hole/depression lower than the rest of the yard, which is deep enough for the pump to work in and to operate the float switch (the switch may require a few hundred millimeters depth). This means that the entire yard does not need to fill up before the pump comes on. The depth should be arranged so that the water level in the sump that is required to start the pump is below the level of the rest of the yard.
Giving the diameter and depth of the tube would be a GREAT help. Also add all the constraints of you problem rather than adding then a bit at a time. A picture of the location of the pump and location of the sensor (If different,) would help..
Edit. This was in response to a question that the OP asked in a second thread that he opened on the subject. (The moderators closed that thread to avoid the confusion that would be caused by multiple threads on the same subject.)
If there is a lower place, then a self starting siphon may work. Basically, two buckets at the same height with a tube between them - all filled with water.

You'll have to think about that one and explain to us how you think a self-starting siphon between to buckets could empty surface water from a low area as described.
Hm. Apart from that I would be billing my neighbour for water treatment and waste disposal, I still maintain that unless you have a lower point (or a hard surface that leads to a lower point) to pump the water to, its just going to flow back in.
And if you have a lower point, you could install a drain to that lower point. Of course, that doesn't mean it would be easy or economic to do so.

Yeah, Google laughed last night and then, at your suggestion, I added the word "two" this morning - Google laughed even harder about siphoning from a flat surface with two buckets. It's a nice novelty trick in a high school lab but not for lifting water off of a flat surface.
It's what the OP should be doing in the first place, dig a sump at lowest point, float switch and pump inside, metal grill over the top - job done. Simple solution, already in use by millions of people.
