Review on 🔍 Dioxide Controller for Digital Gas Monitoring by John Talcott

Works great it can definitely pick up when we leave the house and come back as we have house plants. You can set or disable the alarm threshold. It is set much lower than the OSHA Transitional Normal Maximum. In terms of humidity, it matches our Nest thermostat. However, it is recommended to keep CO2 levels in a building as low as possible for optimal health.
