Meet the CyberMask a DiY poisonous GAS Detection Mask

Our response to the COVID-19 – the CyberMask 🙂 , a DiY toxic / flammable gas detection mask, designed (During the weekend 🙂  @ Ji4ka Coworking.

What is it? 

Recently our Government declared emergency state and since 12.04.2020 we are obliged to wear masks in public. Our Prime minister Boyko Borisov declared that those who cant buy a mask can make a DiY mask . I have decided to go further and add some electronics to the mask. I had a several mini Arduino boards based on Attiny85 (Digisparks), SNS-MQ2 Gas Detection Sensor from Olimex, and a RED notification LED. During the weekend I have put all these components together and wrote a program that reads the Sensor input and based on the reading it triggers an Alarm (in this case and SOS morse code message).

The SNS-MQ2 GAS detections sensors can sense LPG, propane, hydrogen, methane and other combustible substances in the air. I even went further and tested whether the sensor can detect Acetone (As when one has Pneumonia , this gas is exhaled from the lungs in the initial stage of the disease) . It turned out that it actually DOES detect Acetone.

The mask didn’t looked very well with all these wires and boards hanging from it, so I made an enclosure design and cut on a black cardboard, by using Ji4ka’s cutting Plotter. (you can download the template vector files at the end of this blog post.)

Ok, the enclosure is designed but how do we attach it to the actual mask? The simplest way was to use a dual stick tape, but if so , the mask can not be reusable, so I have decided to use val-crow dots and fix the module to the mask in 6 points

The final result once all components were put together into the enclosure was this:

What is needed to build it?

• – SNS-MQ2 from Olimex
• – Digispark Tiny85 (with a microusb connector) (Ebay)
• – RED LED
• – 3.6V LiPo Battery
