Review on 🌡️ Cutting-Edge ERICKHILL Temperature Monitoring System: Real-Time Solution for Greenhouses and Hospitals by Alif Wills

First I go outside to check if the thing works :) The light turns nice green, then we open the windows - improve air circulation, I will use this when I go out to check the air quality in shops and bars. 1 does not usually stay when the CO2 level is above 700. Basically to see how the carbon dioxide level changes and cooperate with the carbon dioxide level when the greenhouse is closed, very satisfied to buy. I hope the battery life is longer
