AtlasScientificRTD.h file

Contains the AtlasScientificRTD subclass of the AtlasParent sensor class along with the variable subclass AtlasScientificRTD_Temp.

These are used for any sensor attached to an Atlas EZO RTD circuit.

Classes

class AtlasScientificRTD
The Sensor sub-class for the Atlas Scientific RTD temperature sensor.
class AtlasScientificRTD_Temp
The Variable sub-class used for the temperature output from an Atlas Scientific RTD temperature sensor.

Defines

#define ATLAS_RTD_I2C_ADDR = 0x66
Default I2C address is 0x66 (102)
#define ATLAS_RTD_NUM_VARIABLES = 1
Sensor::_numReturnedValues; the Atlas EZO temperature circuit can report 1 value.

Sensor Timing

The sensor timing for an Atlas RTD (temperature) sensor

#define ATLAS_RTD_WARM_UP_TIME_MS = 740
Sensor::_warmUpTime_ms; the Atlas EZO temperature circuit warms up in 740ms.
#define ATLAS_RTD_STABILIZATION_TIME_MS = 0
Sensor::_stabilizationTime_ms; the Atlas EZO temperature circuit is stable 0ms after warm-up (stable at completion of warm up).
#define ATLAS_RTD_MEASUREMENT_TIME_MS = 650
Sensor::_measurementTime_ms; the Atlas EZO temperature circuit takes 650ms to complete a measurement.

Temperature

The temperature variable from an Atlas RTD (temperature) sensor

  • Accuracy is ± (0.10°C + 0.0017 x °C)
  • Range is -126°C − 125°C

AtlasScientificRTD_Temp(AtlasScientificRTD* parentSense, const char* uuid = "", const char* varCode = ATLAS_RTD_DEFAULT_CODE) explicit

Construct a new AtlasScientificRTD_Temp object.

Parameters
parentSense The parent AtlasScientificRTD providing the result values.
uuid A universally unique identifier (UUID or GUID) for the variable; optional with the default value of an empty string.
varCode A short code to help identify the variable in files; optional with a default value of "AtlasTemp".

#define ATLAS_RTD_RESOLUTION = 3
Decimals places in string representation; temperature should have 3 - resolution is 0.001°C.
#define ATLAS_RTD_VAR_NUM = 0
Sensor variable number; RTD is stored in sensorValues[0].
#define ATLAS_RTD_VAR_NAME = "temperature"
Variable name in ODM2 controlled vocabulary; "temperature".
#define ATLAS_RTD_UNIT_NAME = "degreeCelsius"
Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
#define ATLAS_RTD_DEFAULT_CODE = "AtlasTemp"
Default variable short code; "AtlasTemp".
