Design and Implementation of a Wireless Automated Water Level Monitoring and Pump Control System

Abstract

Our world is facing excessive water usage either for domestic or commercial purposes and it is a serious issue, which affects the sustainability of our environment. This study investigates the design and implementation of a wireless automatic water level sensor device that can accurately detect and regulate water levels in a designated water tank or similar water storage system. The system first identifies the water level in the tank through the utilization of sensing probes. Output from the probe is encoded and transmitted through radio frequency (RF) signals, which are then received and decoded by the designated receiver. The processed information is displayed on an LCD, providing visual feedback as the system adjusts the operation of the water pump according to the water level data. This design achieves automation through the use of sequential logic, utilizing a microcontroller, an LCD, and a relay-driven motor pump circuit. The water pump is configured to engage autonomously, commencing the filling operation when the water level reaches the empty state or level ONE. It will stop operation and halt the filling process once the water level attains the maximum threshold of level FIVE. The pump will remain in a standby state from level FOUR to level TWO as the water level drops due to usage. This automated system enhances water management by minimizing human intervention while ensuring that the storage tank consistently maintains optimal water levels.
