Very Low-cost MEMS-based Ultrasonic Anemometer for Use Indoors and in HVAC Ducts

This project will develop low-cost, low power, accurate, calibration-free, and compact airflow sensors (anemometers) for measuring: (1) room airflow in occupied commercial buildings; and (2) volumetric air flow in heating, ventilation and air conditioning (HVAC) systems. The technology will save energy by using the collected data to correct current wasteful HVAC malfunctions that result in inefficient systems and uncomfortable buildings. The anemometers will be wireless, able to be inexpensively installed in existing buildings, and operate on a battery for years and communicate wirelessly via the internet to the building's control system. The device will also sense temperature, its orientation, and its location
