TankBot - Smart Liquid Tank Management System

TankBot is an intelligent monitoring and control system for liquid tanks. It tracks liquid levels, manages flow, optimizes energy consumption, and supports programmable schedules. Designed for automated irrigation, water tank management, and industrial liquid storage systems.

Features

• Real-time Monitoring – Measures liquid level, volume, and fill percentage.
• Automated Control – Manages the pump to maintain optimal levels.
• IoT Integration – Syncs with Arduino Cloud for remote monitoring & control.
• Energy Optimization – Reduces consumption with programmable fill schedules.
• Mobile/Web Interface – View tank status and control operations remotely.
