Summary of AUTOSTERI: SMALL AND COMPACT AUTOMATIC UV STERILIZATION SYSTEM FROM DAVID BERSHADSKY
The AutoSteri is an automatic UV sterilization device that detects when a person leaves an area and then disinfects the space using a high-power UV LED. Designed for unattended operation, it targets hygiene-sensitive locations like hallways, offices, elevators, and packages, reducing the need for manual monitoring. Built around an Arduino Nano and simple sensors and drivers, it supports Arduino IDE for programming and can be implemented on a breadboard or custom PCB.
Parts used in the AutoSteri:
- Arduino Nano R3 (breadboard-friendly)
- PIR motion sensor (generic)
- High power UV LED
- 100 Ohm resistor (1x)
- General-purpose NPN transistor (or motor driver/relay)
- Breadboard or custom PCB
- Jumper wires
- Through-hole 5.5 mm power jack
The probability of having microorganisms survive on a surface or item subjected to treatment is very low; decontaminating an object or material makes it safe to handle.
While there are many techniques capable of effectively disinfecting surfaces, not many can be used independently without personnel, thus making the whole process of monitoring and cleaning tiresome.
The new AutoSteri from maker David Bershadsky was designed to handle and take the stress of sterilization off you. The AutoSteri simply detects the presence of a person in a particular place and disinfects the area after the person leaves the place. Such an interesting and highly useful you would agree, particularly during this time of the Covid-19 pandemic where regard to hygiene and sterilization cannot be over-emphasized. The AutoSteri can be used to sterilize almost everything, hallways, offices, elevators, delivery packages, and many more.
