CO₂-sensing to indicate ventilation effectiveness and reduce COVID spread


The new xTAG HaLow Ventilation Sensor directly measures carbon dioxide (CO₂) with an accuracy of ±40 ppm. It is useful in measuring the effectiveness of ventilation in public spaces—critical in reducing the opportunity for COVID-19 to spread within those spaces. The xTAG Ventilation Sensor is unique in its ability to measure both exterior and interior CO₂ as ventilation effectiveness can only be determined when comparing these CO₂ levels. Other sensors can measure only indoor CO₂ levels, compromising their accuracy and the safety of the space that they protect.

xTAG Ventilation Sensors can work with Deviceworx xGATEWAY devices that can connect to ventilation control systems. They can send ventilation quality data to ventilation control systems to ensure that systems turn up ventilation when required, or down or even off when not required. Optimizing ventilation control can lower significant energy and operational costs dramatically.

Deviceworx also supports the real-time collection of CO₂ data using both BLE (xTAG BLE Ventilation Sensor) and USB (xTAG USB Ventilation Sensor). A BLE-connected xTAG supports 2 Mbit/sec Bluetooth Low Energy (BLE) 5.0 connectivity to xGATEWAYs, facilitating the simplest possible xTAG installs where xTAGs can be up to 300 meters from xGATEWAYs and won’t require local power. A USB-connected xTAG supports indefinite operations without the need to replace sensor batteries. A Wi-Fi HaLow-connected xTAG supports the connection of all sensors within a school or building to a single xGATEWAY device (distances up to 1 km) for wireless real-time data acquisition and reporting with minimal infrastructure costs.
