... Datasheet SHT21S 6 Conversion of Signal Output After the low pass filter the sensor provides an output Voltage V which as a portion of VDD then is converted SO into a physical value. Resolution is set to 10 bit for relative humidity and 12 bit for temperature and cannot be changed. The sensor reading is linearized and hence it can be converted to a physical value by an easy linear equation ...
