Measure indoor CO2 levels with the Nexelec Carbon LoRaWAN® CO2 sensor. Designed to enable you to optimise the ventilation levels in indoor spaces, the Nexelec Carbon actively analyses the CO2 levels through the iZiAIR algorithm every 10 minutes. The sensor features an integrated LED indicator to provide a visual alert for occupants when ventilation is required.

Operating on a wireless network, the LoRaWAN® CO2 sensor transmits recorded data by a LoRaWAN® gateway and network server enabling you to remotely access data. Alerts can also be configured to send SMS or email notifications.

With an integrated battery life of up to 10 years, the Nexelec is ideal for Smart Buildings, Offices and Schools. The CO2 sensor features a stylish compact design which can be easily installed.

Ventilation has become an important factor in ensuring safety indoors throughout the COVID-19 pandemic. While measuring indoor air quality cannot detect the presence of the virus, we know that improving air quality can reduce the likelihood of transmission. Get in touch to discuss how the Nexelec Carbon LoRaWAN® CO2 sensor can be part of your COVID-19 safety strategy.
