More fun with CO2 sensors.

Made the sensor for number 2 available. They’re not reading the same at the beginning because I managed to stop recording last take. Didn’t feel like getting them back to ambient CO2 which is like 327 ppm where they live.

After sharing the last video I had many people try to discredit the video asking if I am a doctor or scientist. For the record no on both. More details in the vid..

My question to people who ask if I am a doctor.. What do my credentials have to do with pointing out there is a way to measure CO2 under a mask? A way that science and engineering built. A device sold to the public. With instructions anyone can read.

I have pointed out the flaws in them. Like this vid. Sensor is too big slightly. Let’s too much air out. The sensors measure every couple seconds. Not every half second or something so they do take a bit to respond. The mask I used is dirty. But the leaks more than compensate for any extra holding capabilities the mask picked up from the dirt. I found it under the seat. Leave me alone lol..

But the point of these videos is the device. There are many like it. Purpose built for small spaces. Some go way higher in the ppm range. The number it presents is what you should be focused on. Not me.. just the guy saying hey we have tools. Let’s use them.. the credentials I have people fear are simple ones to have.. ask questions.. seek answers..
