Datasheet SHT21  
Humidity and Temperature Sensor  
. Fully calibrated  
. Digital output, I2C interface  
. Low power consumption  
. Excellent long term stability  
. DFN type package – reflow solderable  
Product Summary  
Every sensor is individually calibrated and tested. Lot  
identification is printed on the sensor and an electronic  
identification code is stored on the chip – which can be  
read out by command. Furthermore, the resolution of  
SHT21 can be changed by command (8/12bit up to  
12/14bit for RH/T), low battery can be detected and a  
checksum helps to improve communication reliability.  
SHT21, the new humidity and temperature sensor of  
Sensirion is about to set new standards in terms of size  
and intelligence: Embedded in a reflow solderable Dual  
Flat No leads (DFN) package of 3 x 3mm foot print and  
1.1mm height it provides calibrated, linearized signals in  
digital, true I2C format.  
With a completely new designed CMOSens® chip, a  
reworked capacitive type humidity sensor and an  
improved band gap temperature sensor the performance  
has been lifted even beyond the outstanding level of the  
previous sensor generation (SHT1x and SHT7x). For  
example, measures have been taken to stabilize the  
behavior at high humidity levels.  
With made improvements and the miniaturization of the  
sensor the performance-to-price ratio has been improved  
– and eventually, any device should benefit from the  
cutting edge energy saving operation mode. For testing  
SHT21 a new evaluation Kit EK-H4 is available.  
Dimensions  
Sensor Chip  
3.0  
SHT21 features a generation 4C CMOSens® chip.  
Besides the capacitive relative humidity sensor and the  
band gap temperature sensor, the chip contains an  
amplifier, A/D converter, OTP memory and a digital  
processing unit.

Material Contents  
While the sensor itself is made of Silicon the sensors’  
housing consists of a plated Cu lead-frame and green  
epoxy-based mold compound. The device is fully RoHS  
and WEEE compliant, e.g. free of Pb, Cd and Hg.

Figure 1: Drawing of SHT21 sensor package, dimensions are  
given in mm (1mm = 0.039inch), tolerances are ±0.1mm. Die  
pad (centre pad) is internally connected to VSS. NC are floating.  
VSS = GND, SDA = DATA.  
For SHT21 two Evaluation Kits are available: EK-H4, a  
four-channel device with viewer software, that also serves  
for data-logging, and a simple EK-H5 directly connecting  
one sensor via USB port to a computer.
