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-conn-icon.png ADC 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-16-icon.png 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. 
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-conn-icon.png Thermistor Properties
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
Value in Ohms of the Thermistor at -25 deg C 
Fc9-type-21-icon.png 0C Thermistor Value
Value in Ohms of the Thermistor at 0 deg C 
Fc9-type-21-icon.png 25C Thermistor Value
Value in Ohms of the Thermistor at 25 deg C 
Fc9-type-21-icon.png 50C Thermistor Value
Value in Ohms of the Thermistor at 50 deg C 
Fc9-type-21-icon.png 75C Thermistor Value
Value in Ohms of the Thermistor at 75 deg C 
Fc9-type-21-icon.png 100C Thermistor Value
Value in Ohms of the Thermistor at 100 deg C 
Fc9-type-21-icon.png 125C Thermistor Value
Value in Ohms of the Thermistor at 125 deg C 
Fc9-conn-icon.png Simulation
Fc9-type-10-icon.png Label
A text label to help you identify the component on the panel. 
Fc9-type-15-icon.png Min. Temp.
Minimum termperature that can be set or displayed on the thermometer slider. 
Fc9-type-15-icon.png Max. Temp.
Maximum termperature that can be set or displayed on the thermometer slider. 
Fc9-type-21-icon.png Scale divisions
Number of numbered divisions shown on the thermometer scale.
