7.4.3 Low Power Sensor Systems Technologies for Environmental Air-Monitoring

S. H. Brongersma
Distributed monitoring of air quality in the environment requires ultra low power components for autonomous systems. These include the actual transducer, an analog interface, some local processing capability and a wireless connection. To power the system one needs a battery or energy harvester in combination with smart power management. The approximate target is an overall system power of 100 microWatt, which leaves only a fraction of that for (bio-) chemical sensing. Although a wide range...
