Ultrasonic sensor HC-SR04 is used to measure distance in range of 2cm-400cm with accuracy of 3mm. The sensor module consists of ultrasonic transmitter, receiver and the control circuit. The ultrasonic ...

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 ...

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 ...

In auto mode When the water level is very low the water pump will automatically be ON, When the water level will reach a very height than the water pump will automatically be OFF, and in manual mode, ...

Abstract: This work is presenting a water level control and monitoring system in a tank, by using the development boards Arduino Uno, NodeMCU ESP8266 and the ultrasonic sensor HC-SR04. The water tank ...
