Powelectrics Offer a CO2 Monitoring Solution to Help Reduce Virus Transmission Indoors

Posted on 19 Jan 2021

According to a recent article by John Hatcher in Smart Buildings Magazine, “There is increasing evidence that carbon dioxide levels in buildings correlate strongly with the airborne spread of infection. Consequently, CO2 monitors could act as the “canary in the coalmine” to mitigate the coronavirus threat.” Read the full article here.

He explains that carbon dioxide is generated by the exhaled air of the people indoors, who could exhale around eight litres of air per minute! This exhalation also contains tiny liquid droplets (aerosols) which, due to their size, can float in the air for a long time. Those droplets will contain any virus particles present in the lungs. The inference is that CO2 levels in rooms and other enclosed spaces may be used as a proxy for COVID-19 transmission risk. One method to mitigate indoor transmission could be to monitor CO2.

CO2 is the fourth most abundant gas in the earth's atmosphere. At room temperature, carbon dioxide (CO2) is a colorless, odorless, non-flammable gas.

High levels are directly correlated to low concentration, low productivity and poor sleep, even causing headaches, increased heart rate and nausea. This should be actively considered when ventilating schools, offices and home environments.

Powelectrics offer easy to install, low-cost SIGFOX IOT devices to monitor CO2 levels, so that ventilation may be adjusted to reduce the spread of virus and maintain a healthy environment.

These SIGFOX ambient transmitters offer a high power battery and embedded CO2, temperature and humidity sensors. They are compact (housed in a 99 x 85 x 32mm IP40 enclosure), easy to install and fully integrated to Powelectrics MetronView cloud. More info and data sheet here.

The device is approved for use on Sigfox networks. Data is reported to Powelectrics MetronView cloud, allowing unlimited users to view data and receive alarms, securely, via any web-enabled device and even integrate data with 3rd party software solutions, such as building management software, using our API.
