Product Summary

SHT1x (including SHT10, SHT11 and SHT15) is
Sensirion's family of surface mountable relative humidity
and temperature sensors. The sensors integrate sensor
elements plus signal processing on a tiny foot print and
provide a fully calibrated digital output. A unique
capacitive sensor element is used for measuring relative
humidity while temperature is measured by a band-gap
sensor. The applied CMOSens® technology guarantees
excellent reliability and long term stability. Both sensors
are seamlessly coupled to a 14bit analog to digital
converter and a serial interface circuit. This results in
superior signal quality, a fast response time and
insensitivity to external disturbances (EMC).
Each SHT1x is individually calibrated in a precision
humidity chamber. The calibration coefficients are
programmed into an OTP memory on the chip. These
coefficients are used to internally calibrate the signals
from the sensors. The 2-wire serial interface and internal
voltage regulation allows for easy and fast system
integration. The tiny size and low power consumption
makes SHT1x the ultimate choice for even the most
demanding applications.
SHT1x is supplied in a surface-mountable LCC (Leadless
Chip Carrier) which is approved for standard reflow
soldering processes. The same sensor is also available
with pins (SHT7x) or on flex print (SHTA1).

Sensor Chip
SHT1x V4 - for which this datasheet applies - features a
version 4 Silicon sensor chip. Besides the humidity and
temperature sensors the chip contains an amplifier, A/D
converter, OTP memory and a digital interface. V4 sensors
can be identified by the alpha-numeric traceability code on
the sensor cap - see example "A5Z" code on Figure 1.
Material Contents
While the sensor is made of a CMOS chip the sensor
housing consists of an LCP cap with epoxy glob top on an
FR4 substrate. The device is fully RoHS and WEEE
compliant, thus it is free of Pb, Cd, Hg, Cr(6+), PBB and
PBDE.

Evaluation Kits
For sensor trial measurements, for qualification of the
sensor or even experimental application (data logging) of
the sensor there is an evaluation kit EK-H4 available
including SHT71 (same sensor chip as SHT1x) and 4
sensor channels, hard and software to interface with a
computer. For other evaluation kits please check

1 Application Information
1.1 Operating Conditions
Sensor works stable within recommended normal range -
see Figure 4. Long term exposures to conditions outside
normal range, especially at humidity >80%RH, may
temporarily offset the RH signal (+3 %RH after 60h). After
return to normal range it will slowly return towards
calibration state by itself. See Section 1.4 "Reconditioning
Procedure" to accelerate eliminating the offset. Prolonged
exposure to extreme conditions may accelerate ageing.

1.2 Soldering instructions
For soldering SHT1x standard reflow soldering ovens may
be used. The sensor is qualified to withstand soldering
profile according to IPC/JEDEC J-STD-020D with peak
temperatures at 260°C during up to 40sec including Pbfree
assembly in IR/Convection reflow ovens.
