Many heating, ventilation, and air conditioning (HVAC) systems control the airflow through the ductwork based on feedback from wireless sensor networks that monitor quantities such as temperature and pressure. Currently, these networks are powered either through wired connections or batteries, both of which have drawbacks. The wired solution has significant installation costs. In addition, the notion of using wired connections has become increasingly outdated by the proliferation of wireless technology in recent years. The battery powered solution is more flexible, but has a shortened lifespan and increased maintenance costs as compared to the wired solution.
