Precision resistors refer to those resistors with high-precision resistance values
Wire wound resistors are made by winding thin metal wires (such as nickel chromium alloy) around a non-conductive core.
When choosing a precision resistor, the following factors need to be considered:
Thermistor is a temperature sensitive component whose resistance value changes with temperature.
The most basic method of measuring a thermistor is to connect it in series with an AD7416ARZ-REEL7 resistor with a known resistance value and apply a stable voltage.
The microprocessor calculates the current temperature based on the measured voltage and the preset thermistor temperature resistance characteristic curve
