A temperature reading circuit is essential for our Peltier temperature control. With the ability to read the Peltier temperature, we can modulate the power input to generate our desired results.
Today the code for reading temperature inputs was finished! This code interprets the temperature-dependent varistor resistance through an analog input from a voltage divider circuit. This code filters the analog inputs through a low pass filter to negate random noise. A temperature-resistance function was generated using Excel so that the temperatures could be found. This function was used as opposed to the more accurate Steinhart-Hart equation to save on computations, while still attaining great modeling within the active range.
