Hardware Overview
How does it work?
Temp&Hum 17 Click is based on the HS3001, a highly accurate, fully calibrated relative humidity and temperature sensor from Renesas. The humidity can be measured within a range of 0 to 100 %RH, while the temperature sensor is designed for a range of -10 to 80 °C. The typical accuracy for humidity is ±1.5 %RH in the measuring range of 10 up to 90 %RH at ambient temperature and ±0.2 °C for temperature between -10 - +80 °C with very low power consumption. The HS3001 digital sensor accurately measures relative humidity and temperature levels. The measured data is internally corrected and compensated for
accurate operation over a wide range of temperature and humidity levels, which brings us to its highlighted feature - user calibration is not required. The entire output consists of only four bytes of data; that's why calculating the corresponding relative humidity in percent and temperature in degrees Celsius is very easy. Temp&Hum 17 Click communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency up to 100kHz and Fast Mode up to 400kHz. The HS3001 is also factory-programmed to operate even in
Sleep Mode. In Sleep Mode, the sensor waits for commands from the MCU before taking measurements and only performs conversions when it receives a Measurement Request command; otherwise, it is always powered down. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
Features overview
Development board
Fusion for TIVA v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of microcontrollers, such as different 32-bit ARM® Cortex®-M based MCUs from Texas Instruments, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over a WiFi network. The development board is well organized and designed so that the end-user has all the necessary elements, such as switches, buttons, indicators, connectors, and others, in one place. Thanks to innovative manufacturing technology, Fusion for TIVA v8 provides a fluid and immersive working experience, allowing access
anywhere and under any circumstances at any time. Each part of the Fusion for TIVA v8 development board contains the components necessary for the most efficient operation of the same board. An advanced integrated CODEGRIP programmer/debugger module offers many valuable programming/debugging options, including support for JTAG, SWD, and SWO Trace (Single Wire Output)), and seamless integration with the Mikroe software environment. Besides, it also includes a clean and regulated power supply module for the development board. It can use a wide range of external power sources, including a battery, an external 12V power supply, and a power source via the USB Type-C (USB-C) connector.
Communication options such as USB-UART, USB HOST/DEVICE, CAN (on the MCU card, if supported), and Ethernet is also included. In addition, it also has the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options for the TFT board line of products and character-based LCD. Fusion for TIVA v8 is an integral part of the Mikroe ecosystem for rapid development. Natively supported by Mikroe software tools, it covers many aspects of prototyping and development thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.
2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.
3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.

*
* # Description
* This library contains API for the Temp&Hum 17 Click driver.
* This demo application shows an example of
* relative humidity and temperature measurement.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization of I2C module and log UART.
* After driver initialization and default settings,
* the app display retrieves the sensor parameters
* such as temperature and relative humidity.
*
* ## Application Task
* This is an example that shows the use of a Temp&Hum 17 Click board™.
* Logs the temperature [ degree Celsius ] and relative humidity [ % ] data.
* Results are being sent to the Usart Terminal where you can track their changes.
