/** * @defgroup libSHT11 SHT11 * @ingroup driver \p Library to read values from the SHT11 sensor on the ScatterWeb sensor node. Currently MSB430 and compatible nodes are supported. Please note there are some early MSB430s without a SHT11! \p The Sensirion SHT11 is a temperature und humidity sensor with a accuracy of 0.4°C and +/- 3.0% (relative humidity at 25°C). \p Note that calculating the (corrected) humidity requires the current temperature, therefore leading to a longer time. \p A function is provided to select the preferred conversion resolution:
| Mode | Value | Resolution | Time |
|---|---|---|---|
| SHT11_high | rel. Humidity | 12 bit | 55ms |
| SHT11_high | Temperature | 14 bit | 210ms |
| SHT11_low | rel. Humidity | 8 bit | 11ms |
| SHT11_low | Temperature | 12 bit | 55ms |
