Homework Help: Suggest a sensor for the following variables?

  1. May 9, 2012 #1
    1. The problem statement, all variables and given/known data
    Suggest a sensor with a signal conditioning can be used for measuring each of the following physical variables "heat, electrical current, angular displacement, pressure and heart beats"?

    2. Relevant equations

    3. The attempt at a solution

    Heat: sensor: thermometer or thermistor
    signal conditioning: voltage divider

    electric current: ??

    angular displacement: ???

    pressure: sensor: RTD
    signal conditioning: wheatstone bridge

    I need some guidance? please tell the sensor for each of these physical variables also which are the suitable signal conditioning and why if possible?!
