Datasheet SHT21
www.sensirion.com Version 4 – May 2014 12/14
Please note that even if SHT1x/7x protocol is applied the
timing values of Table 5 and Table 7 in this SHT2x
datasheet apply.
For the calculation of physical values the following
equation must be applied:
For relative humidity RH
RES
RH
2
S
1256 RH 
and for temperature T
RES
T
2
S
175.7246.85 T 
RES is the chosen respective resolution, e.g. 12 (12bit) for
relative humidity and 14 (14bit) for temperature.
