CO2 sensor | Orchids Forum

· The price is much cheaper than the cheapest CO2 sensor alone ( K30 costs around 100, and MG811 around 50)! People are wondering what this is to do with orchids. It could be just used as a CO2 meter. Or my plan is to use it as a CO2 logger and eventually as the CO2 controller (for CO2 injection). It can be used in 2 ranges: 02000ppm or 010000ppm. The sensor will output the CO2 …

climate change Why are CO2 sensors so expensive when CO ...

· The cheapest \small\mathsf{CO_2} sensor (also from China) I found was around US\35. Otherwise, raw sensors components are around US\100. The only real difference between the raw sensors and scientific instruments are that the instruments are obviously finished units that are certified and calibrated, like (for example) are raw Geiger tubes (US\5) vs calibrated and certified …

Decent inexpensive CO2 sensor Sensors Arduino Forum

· The MQ135 is just about as sensitive to several other gases as it is to CO2 (in fact it is MORE sensitive to CO), and the response depends strongly on temperature and humidity. Unless you use it under carefully controlled circumstances, it is impossible to know what you are actually measuring. You don''t get much for 2.
