The most expensive component was a CO2 sensor which cost $230. The rig uses an Arduino for feedback and control. With a total BOM cost of $350 their solution is cost effective, and provides an ...

Adaptive ventilation systems could prevent airborne disease transmission on cruise ships, recent research suggests. The ...

After their technological success with the carbon dioxide sensor, the team decided to monitor a different greenhouse gas—methane. They equipped a Seaglider with a methane sensor, and the ...

Not only does [EJ]’s controller make use of a temperature monitor for controlling the fan automatically, but there is also a CO2 sensor integrated to improve this aspect of air quality when needed.
