Covid19 took humankind by surprise in 2019. Due to its fast and efficiently spreading nature, we were forced to use face masks and gloves to protect from everything we touch. Now SARS-COV-2 is just one of the viruses in Coronavirus family, there are many more viruses in this family that haven’t jumped to humans yet. This pandemic has just given us an indication to be prepared for these types of pandemics.
Well we can use masks to protect us outside but what about the things we bring home from market or things we exchange with other people. For example: We cannot apply sanitizers on cell phones, cash or paperwork paperwork that doctors exchange with patients or employees exchange with each other.
Also sanitizer usage involves use of chemicals that are harmful to us and the environment as well as it involves recurring cost of buying sanitizers. Well we solve this huge problem with a smart electronics system powered by a microcontroller. We design a compact 360 degree disinfection box using ultraviolet sterilization to solve the issue. The system makes use of uv c tubes to achieve this task. Now UV C has been proven to kill all viruses within a matter of seconds.
Here are proofs of the concept that UV-C is proven to kill coronaviruses
The COVID Cellphone and cash Disinfection box has the following Key Aspects
- 360 Degree Disinfection
- Proven to Deactivate all CoronaViruses
- Automatic Timer based Shutoff and Alerting
- Can Sterilize Mask, Packed Food, Electronics etc
- Variable Sterilization Timer Setting
- Automatic Safety Shutoff
- Easy To Use
- No Water No Chemicals | Environment Friendly
The Atmega controller takes user input for time setting and starts sterilization when start button is pressed. It automatically shuts off when the sterilization time is completed. Also an automatic shutoff system shuts off the sterilization if lid is opened by user between ongoing sterilization.
The system consists of an LCD display with push buttons to operate this machine. The push buttons are used to set the duration of sterilization. After setting the Atmega controller checks if the lid is closed through proximity sensors. After detecting closed lid the controller activates UV tubes for the set duration time to ensure proper sterilization. Once sterilization is complete the controller deactivates the UV tubes and sounds a buzzer to indicate process completion.
Since direct exposure to UV can be harmful the controller also automatically shuts off the UV tubes if the user opens up the box during ongoing sterilization process. This ensures a water and chemical free sterilization process that can help stop the spread of COVID 19.
