Thermistor component
A generic thermistor component that can be used to simulate and create code for any thermistor with a known temperature/resistance curve. Thermistor is connected in a simple potential divider circuit - thermistor between ADC input and 0V, and a fixed resistor between ADC and the positive supply. The component is also used with the EBM003 module, in which case the extra circuitry is already included. Default calibration is for the EBM003 module.

Properties |
|
ADC Channel |
| The ADC channel to which the thermistor circuit is connected. It is assumed that the thermistor is connected between the ADC pin and 0V, with a fixed resistor connected between the ADC pin and +V. | |
|
VRef option |
| Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage VDD - Defines the microcontrollers power supply pin as the max reference, VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage. | |
|
|
Wiring |
| Specifies the arrangement of the Thermistor and Fixed Resistor. Pull Down - Thermistor connected between ADC pin and GND, fixed resistor between ADC pin and VCC. Pull Up - Thermistor connected between ADC pin and VCC, fixed resistor between ADC pin and GND. | |
