Summary of the Circuit

This circuit consists of an Arduino UNO microcontroller board interfaced with a Water Level Sensor. The Arduino UNO is responsible for providing power to the sensor and reading its signal to determine the water level. The sensor's signal pin is connected to one of the analog input pins on the Arduino, allowing the microcontroller to measure the analog voltage corresponding to the water level.

Component List
