Weather sensors and particularly collect weather data by measuring bending and compression stresses in a weather sensor device. The sensors are based upon the principle of bending stresses and the linear variation of stress between the maximum and minimum point. The sensors model deformation of a hollow shaft or rod. The sensors encompass measuring compression, bending, and/or torsional stresses on other cross-sectional shapes using the appropriate relationship for the particular cross-section that finds use in the technology.
