Paani Varyo: Embedded System for Water Level monitoring of household Tanks in Kathmandu 

Abstract

Shortage of water in Nepal is a common phenomenon especially in densely populated
areas such as Kathmandu. Drinking water is supplied by the government and people
usually use underground water for the household purposes. Load shedding is also a
major problem. Apparently, water is stored in and drawn from the tanks placed at the
rooftop of the house and there is no early warning system to monitor the tank water
level when it has reached a critical situation.
􀂳􀀳􀁄ani Varyo: Embedded System for Water Level Monitoring of Household
Tanks in Kathmandu Upatyaka􀂴 is a system that measures the level of water in the
household tanks in real time. The system uses a water level sensor to measure the
level of water, arduino board to read inputs from the sensors and manipulate the
inputs by sending a set of instructions. ESP8266 Wi-Fi Module is used to access
wireless network. The water level is monitored in real time and its data is send to the
application program that resides in the cell phones of people through the wireless
module. The system also notifies the person when the water reaches the specified
level.
The system is developed realizing the limited availability of water and electricity
under the conditions of ever-increasing population growth. Thus the system is most
applicable in daily use as it helps to draw water to the tanks under the constraints of
electricity and water shortage.
