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. Default calibration is for the EBM003 module.

Property reference

Fc9-prop-icon.png Properties
Fc9-type-6-icon.png 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. 
Fc9-type-21-icon.png ADC Bit Resolution
 
Fc9-type-16-icon.png Conversion speed
Clock setting to select how fast the ADC peripheral will perform an ADC conversion. The FRC setting is based on a RC time base and so will vary with temperature and pressure. Other settings are generally based on divisions of the master clock. 
Fc9-type-14-icon.png Acquisition cycles
Number of micro seconds to wait for the ADC input to charge before starting the analogue sample. 
Fc9-type-16-icon.png 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. 
Fc9-type-21-icon.png Resistor Value
Value in Ohms of the pullup series resistor. i.e. The resistor is connected between the ADC pin and the positive supply rail. 
Fc9-type-21-icon.png -25C Thermistor Value
