Hello friends, in this video I show you how to make an automatic hand sanitizer dispenser at home using simple and affordable materials. I made this project especially for school students who want an easy and useful science/electronics model for their project work. The main idea is very simple: when you bring your hand near the sensor, the pump turns ON automatically and dispenses sanitizer without touching the bottle. For this build I use an IR sensor, a 5V relay module, a small water pump, a lithium-ion battery, a switch, pipe, container, and some wire connections. I explain the basic setup so you can assemble it carefully and make it easily at home. This type of touchless dispenser is helpful for hygiene and also a good way to learn how sensors and relay switching work in a practical DIY model. If you want me to make other projects as your choice, comment me in the comment box.
