Homework Help: AS Sensor Coursework

  1. Jan 23, 2004 #1
    Hello there!!
    My AS Sensor Courswork plan is due in a week today and i really dont know what sensor to use and what to do
    The best ive come up with so far is to use a spinning disc with a hole in it in front of a lamp and using a phototransistor and oscilloscope to work out frequency and rotations / second. I really need some more ideas.. so any help would be very welcome.

    It would help if we knew what the requirements were...

    Its hard to explain the requirements on here because we have pages of it!! Its basically a simple all-round test of a sensor designed in a circuit for a particular purpose.. with a slight emphasis on the use of a potential divider or wheatstone network. For anyone familiar with it or thats done it its on the OCR Advancing Physics course.

    Hmm for AS-evel course work you shouldn't really have posted in the College Help forum.

    I think it would be best if you can provide more info :-/

    Sorry. I'm in college so i thought itd make sense!! :/
    I'm really looking for anyone thats doing the course and might be familiar with the sensor coursework. There's some suggested project ideas like measuring water level with a rotary potentiometer and the spinning disc one but i was hoping someone might have a more original concept!!
