Question About Project of Developing an E-Nose for the Detection of Breath VOC Makeup changes
Question About Project of Developing an E-Nose for the Detection of Breath VOC Makeup changes
Hi! We’re building a low-cost e-nose to detect psychological stress from human breath VOCs (Volatile Organic Compounds), using MQ-3, MQ-135, MQ-138, CCS811, and BME688 sensors. The device will feed data to a machine learning model to classify “stressed” vs “relaxed” breath patterns, accounting for…

Measuring the oxygen content of air project
Measuring the oxygen content of air project
I have set up my project and am on my first day of taking results.
1. Does this project have to be done outside? I put the test tubes out overnight and two jars of water froze.
2. Are the test tubes supposed to be just slightly above the surface of the water or fully submerged into the jar of water? I put the test tube at the level of water a little bit down from the mouth of the test tube, but how can I…

not sure what to do!!!
SOOOO... I know the science fair for my school is almost a month away but I'm not sure what to do it on! I know I want to do it on animals but I'm not sure what!!! :?
Re: not sure what to do!!!
Hi! You were thinking about something else (a different thread you started) and are still undecided, and now you're thinking about a project about animals?
Is there a specific kind of animal you are thinking about or interested in and a question that…

incubator help
hello-
my daughter is in 4th grade and is doing her first science fair project - Who's mouth is cleaner a dogs or a humans. She started the experiment and swabbed the dogs mouths and then swabbed the Petri dishes and we've been trying to incubate them but we're having some troubles. Our house is only about 70 degrees so I'm thinking it's not exactly the best environment for the bacteria to grow because most of the dishes have no growth on them and its been 48…

Asking abouut anemometer prototyping from e-waste
Asking abouut anemometer prototyping from e-waste
Originally, we planned to use a Reed Switch as the main sensor in our design. The problem is that in my
country, it is extremely difficult to find Reed Switches in local electronics stores, and online delivery is slow and unreliable. We also tried looking for old devices to salvage the Reed Switch from, but most of the devices available to us either do not contain one or require complicated…

Developing an Artificial Pancreas
Developing an Artificial Pancreas
I'm unsure whether this is an issue with the multimeter or the water itself, but the reading for the tap water is always around 3.4 or something above 3. Compare this to my reading for the distilled water, which is usually around 2.3. I've scoured websites and the official Youtube video, but I can't figure out why this is occurring. Even when I pour in the tap water, the voltage for the distilled water goes down a little,…
