The Temp&Hum 17 Click Board™ is a compact add-on board representing temperature and humidity sensing solutions. This board features the HS3001, a highly accurate, fully calibrated relative humidity and temperature sensor from Renesas. It features proprietary sensor-level protection, ensuring high reliability and long-term stability. Integrated calibration and temperature-compensation logic provides fully corrected RH and temperature values via standard I2C output. No user calibration of the output data is required.
The high accuracy, fast measurement response time, and long-term stability make the Temp&Hum 17 Click Board™ ideal for various temperature and humidity-related applications, ranging from portable devices to products designed for harsh environments.
How Does The Temp&Hum 17 Click Board™ Work?
The Temp&Hum 17 Click Board™ as its foundation uses 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.
The Temp&Hum 17 Click Board™ 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.
The Temp&Hum 17 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Temp&Hum 17 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.

Software Support
We provide a library for the Temp&Hum 17 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe Github account.
Library Description
This library contains API for the Temp&Hum 17 Click Board™ driver.
Key Functions
temphum17_cfg_setup- Config Object Initialization function.temphum17_init- Initialization function.temphum17_default_cfg- Click the Default Configuration function.
Example Description
This library contains API for the Temp&Hum 17 Click Board™ driver. This demo application shows an example of relative humidity and temperature measurement.
The demo application is composed of two sections :
void application_task ( void ) {
if ( temphum17_get_temp_hum( &temphum17, TEMPHUM17_RESOLUTION_14_BITS, &temperature, &humidity ) == TEMPHUM17_STATUS_VALID_DATA ) {
log_printf( &logger, " Temperature : %.02f Crn Humidity : %.02f %%rn", temperature, humidity, status );
} else {
log_printf( &logger, " Measurement ErrorrntStale Datarn" );
}
log_printf( &logger, "-------------------------rn", temperature, humidity, status );
Delay_ms( 1000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe Github account.
Other Mikroe Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.TempHum17
Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Temp&Hum 17 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
