Wearable Gas Sensor Node for Large-Scale Environmental Monitoring

Inhalt:
Low-power consuming, small, selective gas sensors may be used to build wireless, wearable device for large-scale deployment of chemical sensing technologies. In this contribution a battery-powered, Bluetooth Low Energy (BLE) sensor node for the monitoring one of the most important air pollutants is presented. The device can connect to any smart device and uses its geolocalisation capabilities to provide time-and-spatially resolved data of pollutants. The data is displayed on a live map to visulize the air quality in real time.
