Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

This project demonstrates an Automatic Water Level Controller using an Arduino Uno, HC-SR04 ultrasonic sensor, a relay module, and two push buttons. The ultrasonic sensor measures the distance from ...

Objective To create an efficient water level monitoring system using an HC-SR04 sensor and Arduino, enabling real-time data collection, visualization, and potential IoT integration for various ...

The water level indicator project utilizes an Arduino Uno microcontroller, an LCD display, and a Bluetooth module to provide an efficient solution for monitoring water levels and controlling a motor.

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...
