Near Zero Power Gas Sensor for Agricultural IoT Applications

The deployment of sensor networks into resource-limited settings, such as in a farm, is currently limited due to the lack of effective powering solutions for hundreds of scattered sensors. To mitigate such limitations we demonstrated a near-zero power gas sensor that normally sleeps, consuming <100 pW until being awoken by a trigger (target gas molecules) thus ultimately to enable significantly-extended battery-supported lifetime for rare event monitoring in an agriculture application.
