Hello,
Oh, I am not attaching a pump with this project... there is a separate circuit for starting and switching off the pump.
I will install a new float sensor in to the tank and the lower heigh, just to get notification that now water level in the underground tank is low..... so that I can order a new payload i.e water from water company..... or I will add their mobile number so that they will receive sms and send the water tanker at my home.
Thanks
Omair.
