In this water level indicator project, we have used arduino and ultrasonic sensor to know the water level in tank. A relay is used to start the water motor automatically when water level is low.

Water Level Sensor Pinout The working principle of the water level sensor module is very similar to that of a Rain Sensor. The water level sensor has three pins, runs on 5V power, and gives out the ...

Abstract: 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 ...

Water level monitor - Arduino / ESP8266 / ESP32 / Sigfox Watmonitor (Water level monitor) works as central web interface for storing data from sensor nodes. Data were shown to user at dashboard, ...

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 ...

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 ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

Before this, we worked on some water monitoring projects: Simple Water Level Indicator Alarm with Buzzer Automatic Water Level Indicator and Controller using Arduino How to Measure Water Level using ...

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 ...

Watmonitor (Water level monitor) works as central web interface for storing data from sensor nodes. Data were shown to user at dashboard, graphs, tables.
