Dear all,
I like to share my recent project monitoring Air Quality in rooms with multiple sensors using ad-hoc networks.
Air quality (measured by CO2 or VOC levels) can be an indicator of possible virus concentrations in the air. To lower health risks in indoor environments it is important to ventilate rooms regularly. This project could help schools or offices without sufficient mechanical ventilation especially as the temperatures will fall soon.
I hope this could be a educational project for schools and students. Open space offices and benefit too. Every room occupied by many people raises the risk of infections of any kind.
Live data of my 3 BME680 are published on mqtt://broker.hivemq.com:1833 subscribe to: healthy-indoors-project/# currently placed in my home but soon installed in an open space office.
