GSM and Sensor based Digital Time Switch which is a microcontroller based programmable time switch which can drive any electrical machine (like motor, fan, ac, fridge, LED, Cooler, etc.) for particular time for time bound operations. It has two sensors inside the water tank on the TOP and at the Bottom and the GSM Module in the controller system. The controller will automatically drive the motor on the ON TIME given by the user as well as make it OFF when it reaches OFF TIME . During the stipulated controller ON TIME Period, both sensors become active which will make the motor Automatically OFF when water is FULL and Automatically ON when water is EMPTY in the water tank. If power gets OFF and comes again within the controller ON TIME period, then the system will automatically START. Since our controller also has a GSM module inside . Hence, In any case, If power didn’t come in the stipulated time period, user/Ward members can also drive the motor by sending SMS through fixed mobile no.
