Arduino based Smart Water Management

Abstract

Rainwater harvesting is the process to store the rain water in containers before the rain water goes beneath the ground and recharges the underground water table. This paper proposes the design of smart water management system based on Arduino as an IoT application. In the proposed design, once water is collected in ground tank, the ultrasonic sensor is used to sense the level of water. The sensed information is updated on an android application through which user can visualize the water level on a smartphone. According to the level of water in the tank, the motor functioning is controlled, when water reaches near high level of underground tank, motor will be turned on through Blynk application on smartphone to transfer the water in the ground tank to main tank and when main tank is about to fill up it will turn off automatically. When soil of the garden is dry, the soil moisture sensor senses the dryness in soil and automatically start the water pump and water flow through main tank and reach the soil of garden then motor is automatically switched off. Storing the rainwater reduces the surface runoff. This also reduces the surface erosion. By capturing rainwater in reservoirs, the flood problem in large rainfalls is also diminished.
