Downloadable macro reference
|
ReadHumidityInt |
| Samples the humidity from the sensor and returns the relative humidity reading as a integer byte from 0 to 100 | |
 - BYTE
|
Return |
|
|
DataAvailable |
| Checks to see if new sensor data is available. Returns 0 if no new data is available. Returns 1 if new Temperature data is available. Returns 2 if new Humidity data is available. Returns 3 if new Temp and Humidity data is available. | |
| - BYTE
|
Return |
|
|
ReadTemperatureInt |
| Samples the temperature from the sensor and returns the reading in degrees C as an integer from -40 to 120. | |
 - INT
|
Return |
|
|
ControlHeater |
| Controls the in-built heater element to speed up sensor recovery time in case of condensation. Humidity and temperature cannot be read while Heater is active. | |
 - BOOL
|
Active |
| 0 = Off (Sensor Reading Available) / 1 = On (Sensor Reading Disabled) | |
 - VOID
|
Return |
|
|
ReadHumidityReal |
| Samples the humidity from the sensor and returns the relative humidity reading as a float from 0.0 to 100.0. | |
 - FLOAT
|
Return |
|
|
ReadRegister |
| Reads an 8-bit value from one of the registers onboard the sensor IC. | |
| - BYTE
|
Address |
| - BYTE
|
Return |
|
|
ReadTemperatureReal |
| Samples the temperature from the sensor and returns the reading in degrees C as a float from -40.0 to 120.0. | |
| - FLOAT
|
Return |
|
|
WriteRegister |
| Writes a value to a register on the sensor IC. | |
| - BYTE
|
Address |
| - BYTE
|
Data |
| - VOID
|
Return |
|
|
Initialise |
| Configures the I2C peripheral ready for communications. | |
| - BYTE
|
Return |

|
SDA |
| Pin used for SDA (data signal) | |
|
|
SCL |
| Pin used for SCL (clock signal) | |
|
Stop Delay |
| On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications. | |
