The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurements at constant ambient conditions. It is a measure for the noise on
the physical sensor output. It is measured with analog circuit and integrated over 1 second.

For details about recommended humidity and temperature operating range, please refer to section 1.1.

Time for achieving 63% of a humidity step function, valid at 25°C and 1m/s airflow. Humidity response time in the application depends on the design-in of the sensor.
7
Typical value for operation in normal RH/T operating range, see section 1.1. Maximum value is < 0.5 %RH/yr. Value may be higher in environments with vaporized
solvents, out-gassing tapes, adhesives, packaging materials, etc. For more details please refer to Handling Instructions.
8
Temperature response times strongly depends on the design-in of the sensor in the final application. Minimal response time can be achieved when the thermalized
sensor at T1 is placed on a well conducting surface with temperature T2.

1.1 Recommended Operating Condition
The sensor shows best performance when operated within recommended normal temperature and humidity range of 5
60 °C and 20 80 %RH, respectively. Long term exposure to conditions outside normal range, especially at high humidity,
may temporarily offset the RH signal (e.g. +3%RH after 60h at >80%RH). After returning into the normal temperature and
humidity range the sensor will slowly come back to calibration state by itself. Prolonged exposure to extreme conditions
may accelerate ageing. To ensure stable operation of the humidity sensor, the conditions described in the document
“SHTxx Assembly of SMD Packages”, section “Storage and Handling Instructions” regarding exposure to volatile organic
compounds have to be met. Please note as well that this does apply not only to transportation and manufacturing, but also
to operation of the SHT3x-ARP.

connected to VSS.
3.1 Power Pins (VDD, VSS)
The electrical specifications of the SHT3x-ARP are shown in Table 3. The power supply pins must be decoupled with a
100 nF capacitor that shall be placed as close to the sensor as possible see Figure 8 for a typical application circuit.
3.2 Temperature and Humidity Pin
The physical output of temperature and humidity can be read out at separated pins, as shown in Table 6. Data is supplied
as ratiometric voltage output. The specification of the analog voltage signal and its conversion to physical values is
explained in Section 4.
3.3 nRESET Pin
The nReset pin may be used to generate a reset of the sensor. A minimum pulse duration of 350 ns is required to reliably
trigger a reset of the sensor. If not used it is recommended to connect to VDD.

positioning of the pins does not reflect the position on the real
sensor. This is shown in Table 6.
3.4 Die Pad (center pad)
The die pad or center pad is visible from below and located in the center of the package. It is electrically connected to
VSS. Hence electrical considerations do not impose constraints on the wiring of the die pad. However, due to mechanical
reasons it is recommended to solder the center pad to the PCB. For more information on design-in, please refer to the
document “SHTxx Design Guide”.
4 Operation and Communication
4.1 Start-up of the sensor
The sensor starts up after reaching the power-up threshold voltage VPOR specified in Table 3. After reaching this threshold
voltage the sensor needs the time tPU until the first measurement signal is available as voltage output on the respective
output pins. During that time the temperature and humidity pins have an undefined state.
4.2 Conversion of the Signal Output
The physical values as measured by the sensor are mapped to a ratiometric voltage output (VX, x=T, RH as 10 to 90% of
VDD). Prior to conversion into a voltage signal, the physical values are linearized and compensated for temperature and
supply voltage effects by the sensor. Additionally, the voltage output is calibrated for each sensor. Hence the relationship
between temperature and humidity and the voltage output is the same for each sensor, within the limits given by the
accuracy (Table 1 and Table 2).
This allows to describe the relationship between physical values (RH and T) and the voltage output for temperature and
humidity (VX, x=T, RH) through a generic linear formula given by equations (1), (2) and (3); its graphical representation
can be found in Figure 9 & Figure 10.

5 Packaging
SHT3x-ARP sensors are provided in an open-cavity DFN
package. DFN stands for dual flat no leads. The humidity
sensor opening is centered on the top side of the
package.
The sensor chip is made of silicon and is mounted to a
lead frame. The latter is made of Cu plated with
Ni/Pd/Au. Chip and lead frame are overmolded by an
epoxy-based mold compound leaving the central die pad
and I/O pins exposed for mechanical and electrical
connection. Please note that the side walls of the sensor
are diced and therefore these diced lead frame surfaces
are not covered with the respective plating.
The package (except for the humidity sensor opening)
follows JEDEC publication 95, design registration 4.20,
small scale plastic quad and dual inline, square and
rectangular, No-LEAD packages (with optional thermal
enhancements) small scale (QFN/SON), Issue D.01,
September 2009.
5.1 Traceability
All SHT3x-ARP sensors are laser marked for easy
identification and traceability. The marking on the sensor
top side consists of a pin-1 indicator and two lines of text.
The top line consist of the pin-1 indicator which is located
in the top left corner and the product name. The small
letter x stands for the accuracy class.
The bottom line consists of 6 letters. The first two digits
XY (=AR) describe the output mode. The third letter (A)
represents the manufacturing year (4 = 2014, 5 = 2015,
etc). The last three digits (BCD) represent an
alphanumeric tracking code. That code can be decoded
by Sensirion only and allows for tracking on batch level
through production, calibration and testing and will be
provided upon justified request.
If viewed from below pin 1 is indicated by triangular
shaped cut in the otherwise rectangular die pad. The
dimensions of the triangular cut are shown in Figure 12
through the labels T1 & T2.

Table 7 Package outline
5.3 Land Pattern
Figure 13 shows the land pattern. The land pattern is
understood to be the open metal areas on the PCB, onto
which the DFN pads are soldered.
The solder mask is understood to be the insulating layer
on top of the PCB covering the copper traces. It is
recommended to design the solder mask as a Non-
Solder Mask Defined (NSMD) type. For NSMD pads, the
solder mask opening should provide a 60 μm to 75 μm
design clearance between any copper pad and solder
mask. As the pad pitch is only 0.5 mm we recommend to
have one solder mask opening for all 4 I/O pads on one
side.
For solder paste printing it is recommended to use a
laser-cut, stainless steel stencil with electro-polished
trapezoidal walls and with 0.1 or 0.125 mm stencil
thickness. The length of the stencil apertures for the I/O
pads should be the same as the PCB pads. However,
the position of the stencil apertures should have an offset
of 0.1 mm away from the center of the package. The die
pad aperture should cover about 70 90 % of the die
pad area thus it should have a size of about 0.9 mm x
1.6 mm.
For information on the soldering process and further
recommendation on the assembly process please
consult the Application Note
HT_AN_SHTxx_Assembly_of_SMD_Packages, which
