Application Note for Sensirion SHTC1 Xplained Pro Extension Board

Getting Started with the SHTC1 Extension Board and Demo Code

Summary

Many  of  today’s     smart  phones  and  tablets    feature       Sensirion               provides  a  sensor       wing  board   which  is

processors to allow low power always-on sensor data                compatible with Atmel’s Xplained Pro platform. This board

processing. Sensirion is partnering with leading sensor            includes            the  SHTC1    humidity   and  temperature      sensor

hub manufacturer Atmel in their sensor hub initiative, a           which is built for the consumer and mobile market, with its

collaboration to bring together sensor manufacturers and           tiny                2x2x0.8mm3    footprint  and  1.8V  supply     voltage.

companies developing fusion algorithms and create an               Sensirion’s sensor board can be combined with any of the

expandable,  unified  platform  to   prototype  new  sensor        already             available     extension  boards     providing  touch

subsystems for smart phones or wearable devices in a               controls or display capabilities to quickly build powerful

simple, plug-and-play fashion.                                     systems and start developing right away.

Required Hardware and Wiring

To run the demo code, the Atmel SAMD20 Xplained Pro Board and the Sensirion SHTC1 Xplained Extension Board are

needed. The SHTC1 extension board has to be connected to SERCOM extension position 2 (EXT2) as shown in Figure 1.

Functionality of Demo Code

The provided demo code implements communication with the SHTC1 sensor over the I2C bus. Values are read in a loop and

used for detection of breathing on the sensor (so called Air-Touch).

On reset/start, a reference humidity value is calculated. During operation, humidity values are read in a loop and the difference

between current value and reference value is calculated. If the difference exceeds a given threshold, LED0 is turned on.

BUTTON0 can be used to re-initialize the reference value.

In addition, humidity values and calculated dew point values are sent to host PC over USART. When the example from Atmel

studio is running, the output can be read with any serial port terminal program (e.g., hyper-terminal or Tera term) from EDBG

Virtual COM Port.

Code Structure

The code is structured as follows:

  SHTC1 driver (shtc1.c and shtc1.h)- Implements I2C driver for SHTC1 sensor

  Main file (main.c) – Contains an entry point of an example. The code in this file calls initialization routines and

   subsequently starts the main loop, where values from the SHTC1 sensor are read and air-touch is detected

  Helpers (demo_tools.c and demo_tools.h) Contains implementation of helper functions, e.g., printing messages

   back to the terminal (for debugging purposes) and initialization of I2C board support.
