Detailed Descriptions
These are used for the AOSong AM2315 capacitive humidity and temperature sensor.
This file is dependent on the Adafruit AM2315 Library.
Classes
- class AOSongAM2315
- The Sensor sub-class for the AOSong AM2315.
- class AOSongAM2315_Humidity
- The Variable sub-class used for the relative humidity output from an AOSong AM2315.
- class AOSongAM2315_Temp
- The Variable sub-class used for the temperature output from an AOSong AM2315.
Defines
- #define AM2315_NUM_VARIABLES = 2
- Sensor::
_numReturnedValues; the AM2315 can report 2 values. - #define AM2315_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for an AOSong AM2315
- #define AM2315_WARM_UP_TIME_MS = 500
- Sensor::
_warmUpTime_ms; the AM2315 warms up in 500ms (estimated). - #define AM2315_STABILIZATION_TIME_MS = 500
- Sensor::
_stabilizationTime_ms; the AM2315 is stable after 500ms (estimated). - #define AM2315_MEASUREMENT_TIME_MS = 2000
- Sensor::
_measurementTime_ms; the AM2315 takes 2000ms (2s) to complete a measurement.
Humidity
The humidity variable from an AOSong AM2315
- Range is 0 to 100% RH
- Accuracy is ± 2 % RH at 25°C
Construct a new AOSongAM2315_
AOSongAM2315_Humidity(AOSongAM2315* parentSense,
const char* uuid = "",
const char* varCode = AM2315_
Parameters
parentSense
The parent AOSongAM2315 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 "AM2315Humidity".
- #define AM2315_HUMIDITY_RESOLUTION = 1
- Decimals places in string representation; humidity should have 1 (0.1 % RH for the 16 bit sensor).
- #define AM2315_HUMIDITY_VAR_NUM = 0
- Sensor variable number; humidity is stored in sensorValues[0].
- #define AM2315_HUMIDITY_VAR_NAME = "relativeHumidity"
- Variable name in ODM2 controlled vocabulary; "relativeHumidity".
- #define AM2315_HUMIDITY_UNIT_NAME = "percent"
- Variable unit name in ODM2 controlled vocabulary; "percent" (percent relative humidity)
- #define AM2315_HUMIDITY_DEFAULT_CODE = "AM2315Humidity"
- Default variable short code; "AM2315Humidity".
Temperature
The temperature variable from an AOSong AM2315
- Range is -40°C to +125°C
- Accuracy is ±0.1°C
Construct a new AOSongAM2315_
AOSongAM2315_Temp(AOSongAM2315* parentSense,
const char* uuid = "",
const char* varCode = AM2315_
Parameters
parentSense
The parent AOSongAM2315 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 "AM2315Temp".
- #define AM2315_TEMP_RESOLUTION = 1
- Decimals places in string representation; temperature should have 1. (0.1°C for the 16 bit sensor)
- #define AM2315_TEMP_VAR_NUM = 1
- Sensor variable number; temperature is stored in sensorValues[1].
- #define AM2315_TEMP_VAR_NAME = "temperature"
- Variable name in ODM2 controlled vocabulary; "temperature".
- #define AM2315_TEMP_UNIT_NAME = "degreeCelsius"
- Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
- #define AM2315_TEMP_DEFAULT_CODE = "AM2315Temp"
- Default variable short code; "AM2315Temp".
