About the Practice
Problem Statement:

Coming from an agricultural area, Prem observed the difficulty of farmers faced at night being when they had to go far from home to faraway fields to switch on or off the pump used to water the fields. The farmer also needs to know, sitting at home, if the power supply is on at the pumping station so that he can decide whether to switch it on or cut it off if it is running. The mobile phone operated switch he has designed, addresses all these requirements by enabling farmers to know the electricity status and remotely switch the pump as required, from the comfort of his home and that too without spending any money.


The mobile phone operated switch is an instrument with an attached mobile phone and modified circuit, which can toggle a device between switch-off and switch-on conditions and also be used as a conduit to know the status of a remote operating device.
