# ESP-Water-Tank-Controller 

An ESP8266-based water tank monitoring and control system using ESPHome and Home Assistant. This project monitors water levels and controls relays to manage the water pump.

## Features

* Monitors water levels at 5 different points.

* Controls water pump based on water levels.

* Measures water temperature using DS18B20 sensor.

## Hardware Requirements

* ESP8266 (D1 Mini)

* DS18B20 Temperature Sensor

* Relays
