Water Level Sensor: Connected in a voltage divider configuration with a fixed resistor (10kΩ). The junction of the sensor and the resistor is connected to an analog input pin (A0) of the Arduino to ...

Learn how to use a capacitive sensor and an Arduino to measure and display the level of liquid in a container. Follow the steps to make, calibrate, and test the circuit.

LEDs on the Arduino can be programmed to indicate if the sensor is or isn’t immersed by the liquid to determine liquid levels. The devices are compact, allowing them to be deployed within constrained ...

Circuit Fig. 3 shows the circuit diagram of the automatic water level indicator cum controller. It is built around an Arduino Uno board (MOD1), three LEDs, a 5V SPDT relay, and other components. First ...

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.

Although simple in theory – an air bubble and conductive liquid sealed in a chamber surrounded by electrodes – electronic levels are more complex in practice. If the liquid is an electrolyte, it needs ...
