I’ve been looking for a sensitive CO2 sensor (0ppm - 100ppm) but haven’t seen any, maybe sparkfun can find one easier.
thanks.
That sensing range is very tricky & I’m not sure you’ll easily be able to obtain one. If you needed a higher sensing range, you could easily get one eg:
Yeah, that range is tricky. Underwater CO2 detectors can sense that range but it’s a completely technology and expensive.
