CO Sensor

Hi.

I'm starting with a CO sensor project.

I've been researching for a while and I found that a level higher than 1 ppm starts to be dangerous for human beigns.

On the other hand I've crossed all the internet and I found that most of the sensors has 1 ppm of resolution or even more....

Does someone knows if there are some gas sensors with a better precission?

Kind regards

CO levels

I’ve been researching for a while and I found that a level higher than 1 ppm starts to be dangerous for human beigns.

I’m not a medical doctor or so but Wikipedia says that concentrations above 100ppm are a risk for the human health.

I’m pretty sure you can get sensors with precisions better than 1ppm but I doubt that they’ll fit the hobbyist budget.
