Review on 🌡️ Discover the Versatile CO2Meter AZ 0004: Temperature & Relative Humidity Monitoring Solution by Reginald Hamilton

I'm a big fan of cutting-edge research. When I learned that even moderate levels of CO2 can negatively impact higher-level cognitive functions, such as in software development, I became curious. When David Heinemeier Hansson started talking about CO2 and started finding the same studies I was very intrigued and checked it out. First, this is a really great meter. It does a great job of passively measuring indoor CO2 and alerting you to higher levels. But secondly, it really helps to make informed ventilation decisions. For example, in one-room apartments without air conditioning, the air circulation is really very bad. While the gauge was originally used to check if the environment was bad, I started using it to see if I was introducing enough air to break up the buildup. Just opening the windows and letting air in and out was enough to bring the CO2 in the ambient air down from 1200ppm to 800ppm and with a fan and a wider window opening I can keep the ambient at around 500 parts all the time per minute hold million. I don't have an alarm anymore, but I keep an eye on it and usually have a policy of leaving the window open at all times, just for air circulation. Obviously this isn't the right step for everyone, but if you want to improve your brain power, buy a meter and start popping windows. Fresh air is really great. I don't know how well this is advertised, but this device has a very nice extra feature: a backup battery to save settings. This means you can turn it off and take it to other outlets/locations and test CO2 there without having to change the alarm settings or time every time.
