The Infrasound sensors are precision instruments designed to detect and measure low frequency atmospheric pressure waves, known as infrasound, that fall below the range of human hearing, typically under 20 Hz. These waves can travel long distances through the atmosphere and are produced by a variety of natural and human-made sources including distant Industrial explosions, volcanic eruptions, severe weather systems, meteors, rocket launches, and other energetic phenomena. Detection and analysis
It is required to design and develop a high-sensitivity atmospheric microbarometer Infrasound sensor that can measuring infrasonic pressure fluctuations in the frequency range of approximately 0.01 Hz to 20 Hz.

It is required to design and develop a high-sensitivity atmospheric microbarometer Infrasound sensor that can measuring infrasonic pressure fluctuations in the frequency range of approximately 0.01 Hz to 20 Hz. The sensor should address the complete hardware architecture, including: (a).Pressure sensing mechanism. (b).Mechanical transducer design. (c).Differential pressure measurement technique. (d).Low-noise analog front-end electronics. (e).Temperature compensation. (f).Long-period pressure equalization system. (g).Environmental enclosure. (h).Wind-noise reduction interface. (i).Calibration methodology. The design should aim to detect very small pressure variations while maintaining long-term stability, low drift, and high signal fidelity.
