Tank Overflow Indicator
A Tank Overflow Indicator using Arduino, a water sensor, and a buzzer that alerts the user by buzzing when the water tank overflows.
Description
The Tank Overflow Indicator is designed to alert when a water tank overflows using an Arduino, a water sensor, and a buzzer. The water sensor is placed at the top level of the tank. When the water level reaches the sensor, it sends a signal to the Arduino. The Arduino processes the signal and activates the buzzer, producing a sound to alert the user about the overflow. This project helps prevent water wastage and potential overflow damage.

A Visitor Counter automatically counts the number of people entering or leaving a room using an IR sensor. The count is displayed on a 16×2 LCD, and a buzzer can alert when a specific limit is reached. This project is widely used in shops, libraries, offices, and events to monitor occupancy. It demonstrates sensor interfacing, counting logic, and real-time display using Arduino.

A digital ruler is an electronic measuring device that provides precise measurements of length, width, or depth. Unlike traditional rulers or tape measures, digital rulers use sensors and electronic displays (often LCD or LED) to show measurements accurately, usually in both metric (mm/cm) and imperial (inches) units. They are widely used in engineering, design, woodworking, tailoring, and education where precision is critical.
