Acoustic ambient temperature and humidity sensing
Acoustic ambient temperature and humidity sensing based on determination of sound velocity is described, in addition to sensors, algorithms, devices, systems, and methods therefor. An exemplary embodiment employs sound velocity in the determination of ambient temperature and humidity. Provided implementations include determinations of sound velocity based on time of flight of a coded acoustic signal and/or based on resonance frequency of a Helmholtz resonator.
