    Default help me ....

    hi friends... i m working on a project which requires a pressure sensor and the pressure is due to air hitting the sensing material. now using this sensor i want to know the relative change in the velocity of air. so can u help me with the type of sensor and where can i find it near ambala or chandigarh. please reply fast..

    i dont think you could find a pressure sensor so sensitive that it can generate voltage because of air pressure....... if its not necessary to go with pressure sensor then better go with simple wind fan. calculate the rpm to get velocity.

    i had used SCP1000 from vti which is a pressure sensor w/ tolerance of ~300 Pa.
    Calculating velocity with pressure sensor is very unknown approach at least to me. You will use pressure had you taken account of change of atmospheric pressure with altitude(i consider this application for moving object),
