Nano Ganesh is a remote control system for controlling water pumps by mobile phone. Once the device is connected to a water pump by attaching it to the electric starter, farmers can use their mobile phone to access to their water pump remotely. Using a unique code number, farmers can turn the pump on and off, monitor the pump, and check on the pump's power supply without ever having to leave their home to go to their fields. Calls made to the pump are free to the farmer. The device has been designed to help farmers save wasted time while more efficiently manage their water pumps, thereby potentially reducing water and energy waste, and increasing crop yields. Every model, except for the basic, low-cost model, includes a charging dock for the mobile phones that are connected to them, so that farmers do not need to collect their phone for charging every few days. Some models also can be connected to an external battery to allow for controlled charging of the onboard mobile phone and also to power the device's internal memory.
