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 |

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. | |
