UV-Light-Sanitizer

Inspiration

In Covid19, its all about survival of the fittest, it is important to keep yourself clean and your personal devices clean, UV Light is a very good way to disinfectant you daily devices you use.

What it does

UV-C light container to neutralize virus & germs controlled by a Raspberry Pi. A couple of IMPORTANT notes:

How I built it

Parts:

Raspberry Pi 4 7 inch touch screen (ther are many options, but I used the official one from Raspberry Pi). Raspberry Pi relays (that can be actiated with 3.3V. I used this one: https://www.amazon.com/gp/product/B0057OC6D8/ref=ppx_yo_dt_b_asin_title_o09_s01?ie=UTF8&psc=1 UVC light (many options on eBay). I used 4 lights (two on the bottom and two on the top), 8 watts each and have a wavelenght of ~280nm Cooler. Aluminum foil Metal shield around the box to prevent UVC light leaking out (it's not visible to the human eye).

Challenges I ran into

Containing the UV rays within the box

Accomplishments that I'm proud of

UV-C light container to neutralize virus & germs controlled by a Raspberry Pi. A couple of IMPORTANT notes:

If you ever build something like this, make sure the box is 100 % protected with the appropriate material to avoid UVC leakage (it goes through most plastics). Direct exposure to UVC is unsafe. I de-activated the UVC lights in this video as I am still waiting for a metal shield/cover to arrive that will go around it.

To my knowledge, it's unclear if UVC has effects on COVID19, but research seems promising and some companies have claimed some success.

For neutralizing virus & germs, it's a function of how long they are exposed to the light, the wavelenght of the light, how powerful the lights are, and how close the lights are to the items.
