Abstract
Water is considered a valuable resource and covers about 70% of the earth's surface. The tight schedule prevents regular
checking of the domestic water tank level while refilling the used ones. This often leads to a waste of water and increased monthly revenue
payments to power utility companies. Consequently, this paper presents a water level controller with SMS capability aimed
at measuring water level smartly such that when a tank is filled, a message would be automatically transmitted as an alert to the owner
using GSM for immediate response. The method involves the interconnection of a water container that serves as a tank with another open
container serving as a Bore-hole and a microcontroller-based device with its integrated development to generate a communication
message. A flowchart that shows the procedural steps involved was developed. On completion of the prototype, components and sub-circuits effectiveness as well as experimental testing of the system's effective operation were carried out. Some anticipated water level
(AWL) were selected at an interval of 2 centimeters (cm) starting from 3cm and the corresponding Message Operating water level (MOWL)
were obtained with error deviations not greater than 0.17cm. Thus the average AWL, average MOWL, and error deviation are 11cm,
10.7cm and 0.1cm. The prototype device thus operated effectively.
