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.

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 ...

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 ...

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 is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

This will cause the sensor switch to mal-function. Meanwhile, since there are no means to detect the water level of the basement water tank, it is possible that the pumping motor will be burned if ...
