Need to chose a sensor for a presentation

  1. May 12, 2008 #1
    As stated I need to chose a somewhat simple sensor (needs to be fully explained in 3 slides) for a short presentation. I cannot use anything we have discussed at length (accelerometer, strain gauge, thermocouple, LVDT).

    Any ideas?

    Thanks

    Here's some simple ones:

    Voltmeter
    pH meter
    Osmolarity meter
    pressure gauge
    photosensor

    If you want to get sneaky, talk about a 'chip log' or a 'log line' to measure velocity- that's about as simple as it gets.
