Optimizing Agricultural Water Management: IC 555 Controlled DC Motor With Soil Moisture Sensor For Sustainable Irrigation

Abstract

This paper discusses an Automatic Irrigation System employing a 555 IC M08A (IPC-7351) and the Soil Moisture Sensor aim to revolutionize water management in agriculture and household applications, respectively. Utilizing the 555 timer IC as a timing mechanism, the irrigation system regulates watering intervals based on soil moisture levels, activating the water pump via a relay controlled by the 555 IC when the moisture falls below a set threshold. Operating in astable mode, the 555 IC generates a square wave, which controls the relay to initiate irrigation, optimizing water usage and promoting sustainable irrigation practices to address escalating water scarcity issues. On the other hand, the Water Level Controller addresses excessive water wastage in households due to overflow from overhead tanks by employing sensing probes and electronic circuits that detect water level fluctuations. This system automates the water pumping process to overhead storage tanks, allowing users to select desired water levels for pumping rather than relying on conventional filling methods. Together, these systems offer efficient water management solutions without the need for complex microcontrollers, conserving water and fostering environmentally friendly practices for a sustainable future.
