Properties |
|
Themistor |
|
Ohms Value at 25C |
| Thermistor resistance at 25C is usually found on the thermistor datasheet. If you have a 10K thermistor, that that will be the value at 25C | |
|
|
Beta Value |
| Beta value is usually found on the thermistor datasheet | |
|
|
Fixed Resistor |
|
|
Ohms Value |
| Value of pullup or pulldown fixed resistor in ohms | |
|
Resistor Biasing |
| Pullup - Fixed resistor is connected to + of the supply Pulldown - Fixed resistor is connected to 0V of the supply | |
|
|
ADC |
|
Channel |
| Analogue Input Channel - Which pin is the analogue input connected to? | |
|
VRef voltage |
| Used by the GetVoltage or GetString component macros to take an ADC reading and convert it into a Voltage. +VRef voltage x 10mV Default 500 = 5.0V | |
|
|
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. | |
|
|
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. | |
|
|
Acquisition cycles |
| Number of micro seconds to wait for the ADC input to charge before starting the analogue sample. | |
|
|
Bit Depth |
| Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095 | |
|
|
Temperature |
|
|
Offset x 100 |
| +/- x100 Enter temperature offset x 100 For example, temperature measured with an accurate thermometer is 22.0. Returned is 23.4, which is 1.4 degrees too high. For offset enter -140. | |
|
OffSet |
|
|
Result Decimal Places |
| Number of decimal places (0 to 4) for temperaure results | |
