A Corona traffic light as a total IoT solution

The use case in this podcast episode revolves around a Corona traffic light that helps optimize indoor air monitoring and makes manual documenation a thing of the past. Sentinum’s traffic light is part of an overall IoT solution and works with the smart 1NCE SIM card. This is integrated directly on a circuit board and enables mobile connectivity. Users of the solution can directly access the data on different devices and react accordingly. The traffic light is a sensor, the so-called Febris sensor, which is ideally placed in the center of indoor spaces to determine the air values in the best possible way. The sensor determines the measure of exhaled air via the CO2 content. The data obtained is used to infer the amount of aerosols present in the air. An elevated CO2 level indicates an increased aerosol load and, conversely, an increased risk of infection. According to the measured values, the Corona traffic light reacts with green, yellow or red light and – in the last two cases – requests ventilation. The field of application? Wherever people come together and ventilation is necessary – whether in offices, schools, hospitals, restaurants or even industry. Commissioning takes only a few seconds: Attach the traffic light, insert the battery and you’re ready to go. No integration into other networks or intervention in local IT and communications infrastructure is necessary. However, the sensor can also be easily coupled with existing ventilation infrastructures. Both the Sentinum sensor and 1NCE’s smart connectivity solution are versatile and can be easily transferred to a wide range of hardware. In this use case, the linking of things is associated with immediate, tangible added value for the end customer – it provides security, saves time, operates in a power-saving manner, reduces operating costs, and expands existing hygiene concepts for building managers and co.
