Automatic Sanitizer Dispenser

Automatic Sanitizer Dispenser

The Automatic Sanitizer Dispenser is a non-contact, alcohol-based sanitizing solution that enhances hygiene and safety in public and private spaces. Designed to reduce the spread of viruses and bacteria, this smart device automatically dispenses sanitizer when it detects a hand using an IR sensor, ensuring touch-free operation. It is ideal for use in hospitals, schools, offices, retail outlets, and homes.

At the heart of the system is an Arduino Nano microcontroller, which receives input from an IR sensor. When a user places their hand near the sensor, the controller triggers a relay module to power the water pump. Consequently, the pump dispenses a controlled amount of hand sanitizer through a nozzle. This automation reduces human contact and enhances safety.

Moreover, the system uses a 5V DC power supply and includes a breadboard and jumper wires for quick prototyping. Because the pump only activates when needed, the system also conserves sanitizer, making it both economical and eco-friendly.

Unlike traditional soap dispensers, this device uses an alcohol-based solution that evaporates quickly and does not require water. Studies have shown that sanitizers with over 70% alcohol effectively kill most viruses, including coronaviruses. Therefore, the automatic sanitizer dispenser not only promotes better hygiene but also supports public health in critical environments.

In conclusion, this project demonstrates how simple components and embedded systems can be combined to create a practical and life-saving tool. It is easy to assemble, cost-effective, and essential in today’s hygiene-conscious world.
