Re: Detector Building C
Hey so i was wondering how should we go about doing the "build" portion of detector design. me and my partners were thinking just to make a linear regression plot but that seems rather obvious. i feel like we are missing something. sorry if this is a stupid question i havent ever done this event. one of my coaches told me to use "steinhart hart" equation but i dont know how to implmenent that because there are so many unknown variables. thank you for your responses.

Re: Detector Building C
Depends which sensor you are using. Most people use a thermistor, which is best modeled by the Steinhart-Hart equation. The whole idea is to solve for the values of a, b, and c by taking three measurement points during the calibration time. This is how you would do it for state level rules because you wouldn't have the time to make an entire regression model during the 20 minutes of calibration. Linear regression isn't sufficient because thermistors are not linear devices, so if you're running regionals level rules where you bring your own thermometer, you'll be fine with making a cubic or quartic regression first at home.tvremotebad175 wrote: ↑December 23rd, 2020, 4:09 pm Hey so i was wondering how should we go about doing the "build" portion of detector design. me and my partners were thinking just to make a linear regression plot but that seems rather obvious. i feel like we are missing something. sorry if this is a stupid question i havent ever done this event. one of my coaches told me to use "steinhart hart" equation but i dont know how to implmenent that because there are so many unknown variables. thank you for your responses.

Re: Detector Building C
Hello! For our event, we would be following the mini-model, so there is no build portion. Im a bit confused on how this would work, since usually the tests are really generic about topics we learn, but for this, would we still be learning more about how to build it, and if so, what are some resources you would recommend for us to use? Please let me know!
