Can using IoT technology to measure the CO₂ level in buildings help prevent coronavirus infections? An innovative solution creates transparency and provides an opportunity to take action.

As part of the coronavirus pandemic regulations, retailers must limit the number of customers in their stores. A smart access control management with digital lightings at the entrance indicates whether the maximum number of people in the store has been reached and sounds an alarm in case of unauthorized access.

With wireless sensors that measure the temperature, humidity, brightness and CO2 content of indoor air, the Internet of Things provides more security, comfort and transparency in schools, hospitals and large offices.

Logistics service provider Rhenus and Telekom have developed a smart IoT level measurement system to enable them to collect their data tons at the optimum time. The task: to store confidential paper documents securely.

The wireless standard NarrowBand IoT (NB-IoT) makes smart metering more efficient. And now a large measurement test has shown that the transmission technology for building is more effective than all previous solutions.
