2. Soldering the headers
™
Before using your click board
to solder 1x8 male headers to both left and
right side of the board. Two 1x8 male headers
are included with the board in the package.

Temp&Hum click
1. Introduction
Temp&Hum click carries ST’s HTS221
temperature and relative humidity sensor.
The chip comprises a capacitive sensing
element and a 16-bit ADC. The board
communicates with the target MCU through
mikroBUS™ I2C interface (SCL, SDA),
with an additional interrupt (INT) which
you can set as an alarm when a specied
temperature or humidity value is reached.
Designed to use a 3.3V power supply only.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the 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. Essential features
Temp&Hum click has temperature
measurement accuracy is ±1°C within a
0-60°C range. The precision is increased to
±0.5°C in a narrower range from 15 to 40°C.
The relative humidity measurement range is
from 0 to 100% with ±6% accuracy (or ±4.5
in 20-80% range) The measurements are
outputted in a 16-bit resolution.
