SHT4x

This procedure activates the heater at 200mW for 1 second. Removes any condensed/sprayed water from the sensor surface. Although condensed water is not a reliability/quality problem for the sensor, it will cause the sensor to be unresponsive to changes in RH in the air as long as there is liquid water on the surface. Note: After this procedure, the temperature and humidity readings will not be accurate for some time as the sensor needs to cool down to ambient temperature.
