This document describes an agro electronics water chamber on-off controller system that uses sensors and a microcontroller to automatically control a solenoid valve and water flow. The system aims to efficiently control watering based on soil moisture levels detected by a soil sensor and water levels detected by a water sensor. When sensors detect appropriate conditions, a microcontroller sends a signal to open or close the solenoid valve and regulate water flow. This automatic irrigation system helps conserve water and reduces manual labor.
