    Hi,

    I am currently working on a project and I would like to see if I am on the right track.
    Using a 9V battery supply I have a hall effect sensor (2SS52M, Hall Effect Sensor, Omnipolar, 2.5mT, 3.8 → 30 V dc, 3-Pin TO-92) which will output to a Schmitt trigger (TC4S584F(F)).
    I want to know, is my output voltage from the schmitt still +9V?
    with these values is my high V point approx. 2.0V and low V point approx. .6V?
    Basically I want the hall effect sensor to light an LED when magnetic flux leakage has been detected. Any help greatly appreciated! :)

    Your circuit diagram does not agree with the datasheets for either the Hall sensor or the Schmitt trigger. See attached datasheets.

    The Hall device is a current-sinking output, which means you supply a voltage supply to the output through a current-limiting resistor. The Schmitt trigger has no provision for positive feedback and has no negative input terminal.

    Please revise your schematic and try again.
