mikroElektronika SHT1x click User manual

1. Introduction
SHT1x Click is an accessory board in
mikroBus™form factor. It includes a
digital humidity and temperature sensor
SHT11. A unique capacitive sensor element
is used to measure relative humidity while
the temperature is measured by a band-
gap sensor. Serial I2C interface and factory
calibration, allow easy and fast system
integration. Board is set to use 3.3V power
supply by default. Solder PWR SEL SMD
jumper to 5V position if used with 5V
systems.
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all the pins are aligned
correctly, push the board all the way
into the socket.

4. Getting The Data
Communication with the SHT11 sensor is
done using I2C interface. Temperature can
be represented in 12-bit or 14-bit format
in operating range from -40 to +100°C with
accuracy of !0.5°C at room temperature.
Humidity can be represented in 8-bit or
12-bit resolution with !3% accuracy.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down, so that
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.

Before using your click board, make sure
to solder the provided 1x8 male headers
to both sides of the board. Two 1x8 male
headers are included with the board in
the package.

Once you have done all the necessary
preparations, it’s time to get your click
board up and running. We have provided
the examples for mikroC, mikroBasic and
mikroPascal compilers on our Libstock
website. Just download them and you are
ready to start.
6. Power supply selection
On-board PWR SEL
zero-ohm resistor (SMD
jumper) is used to
determine whether 5V
or 3.3V power supply is
used. This resistor is provided in 3.3V position
by default. In order to use SHT1x click with
5V development system, it is necessary to
resolder this jumper to 5V position.
