SHTC3 - Temp&Hum 9 Click (Mikroe)

Summary

This project shows the driver implementation of an I2C temperature and humidity sensor using the SHTC3 sensor with Silicon Labs Platform.

Temp-Hum 9 click is a smart temperature and humidity sensing click board™, packed with features that allow simple integration into any design. It can measure a wide range of temperature and relative humidity values with high accuracy. This Click board™ is an ideal solution for development of a range of different applications, including battery-operated weather stations, thermostats and humidistats, microenvironment centers, respiratory therapy applications, air conditioners, and other similar applications.

Required Hardware

• BGM220 Bluetooth Module Explorer Kit (BRD4314A)

• Or SiWx917 Wi-Fi 6 and Bluetooth LE 8 MB Flash SoC Pro Kit (BRD4002 + BRD4338A)

• Temp&Hum 9 Click board based on SHTC3 sensor

Hardware Connection

• If the BGM220P Explorer Kit is used:

  The Temp&Hum 9 Click board supports MikroBus, so it can connect easily to the Explorer Kit via MikroBus header. Assure that the 45-degree corner of Click board matches the 45-degree white line of the Explorer Kit.

  The hardware connection is shown in the image below:

Setup

You can either create a project based on an example project or start with an empty example project.

Create a project based on an example project

1. From the Launcher Home, add your device to My Products, click on it, and click on the EXAMPLE PROJECTS & DEMOS tab. Find the example project filtering by shtc3.

2. Click Create button on the Third Party Hardware Drivers - SHTC3 - Temp&Hump 9 Click (Mikroe) example. Example project creation dialog pops up -> click Create and Finish and Project should be generated.

   

3. Build and flash this example to the board.

Start with an empty example project

1. Create an "Empty C Project" for the your board using Simplicity Studio v5. Use the default project settings.

2. Copy the file app/example/mikroe_temphum9_shtc3/app.c into the project root folder (overwriting existing file).

3. Install the software components:

   • Open the .slcp file in the project.

   • Select the SOFTWARE COMPONENTS tab.

   • Install the following components:

     If the BGM220P Explorer Kit is used:

     • [Services] → [Timers] → [Sleep Timer]
     • [Services] → [IO Stream] → [IO Stream: USART] → default instance name: vcom
     • [Application] → [Utility] → [Log]
     • [Third Party Hardware Drivers] → [Sensors] → [SHTC3 - Temp&Hump 9 Click (Mikroe)] → use default configuration

     If the SiWx917 Wi-Fi 6 and Bluetooth LE 8 MB Flash SoC Pro Kit is used:

     • [WiSeConnect 3 SDK] → [Device] → [Si91x] → [MCU] → [Service] → [Sleep Timer for Si91x]
     • [WiSeConnect 3 SDK] → [Device] → [Si91x] → [MCU] → [Peripheral] → [I2C] → [i2c2]
     • [Third Party Hardware Drivers] → [Sensors] → [SHTC3 - Temp&Hump 9 Click (Mikroe)] → use default configuration

4. Install printf float

   • Open Properties of the project.

   • Select C/C++ Build > Settings > Tool Settings >GNU ARM C Linker > General. Check Printf float.

     

5. Build and flash this example to the board.

Note:

• Make sure that the Third Party Hardware Drivers extension is installed. If not, follow this documentation.

• SDK Extension must be enabled for the project to install "SHTC3 - Temp&Hump 9 Click (Mikroe)" component.

How It Works

The example performs simultaneous temperature and relative humidity measurements and logs both values via serial output.

You can use Putty or another program to read the serial output. The BGM220 Explorer Kit board uses a baudrate of 115200 by default. You should expect a similar output to the one below.

Report Bugs & Get Support
