Temp Hum 11 click

Temp-hum 11 click is a temperature and humidity sensing Click boardâ„¢, equipped with the HDC1080, a high accuracy digital humidity, and temperature sensor. Its key features are its low power consumption, and the measurement accuracy achieved with that much energy.

Click library

Software Support

We provide a library for the TempHum11 Click 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for TempHum11 Click driver.

Standard key functions :

Example key functions :

Examples Description

This click has two sensors which can be set to sample measurements with the resolution of 8, 11 or 14 bits, based on the measurement time. Calibration coefficients that are applied to the measured value and the results are stored in the MSB/LSB format, on the output registers. These values are then used in formulas so that the final temperature or relative humidity data can be calculated.

The demo application is composed of two sections :

Application Init

Initializes driver init, test comunication and configuration chip for measurement.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
TEMPHUM11_MAP_MIKROBUS( cfg, MIKROBUS_1 );
temphum11_init( &temphum11, &cfg );
// Test comunication
{
log_printf( &logger, "--- Comunication OK!!! ---\r\n" );
}
else
{
log_printf( &logger, "--- Comunication ERROR!!! ---\r\n" );
for ( ; ; );
}
temphum11_default_cfg( &temphum11 );
log_printf( &logger, "--- Start measurement --- \r\n" );
Delay_ms( 500 );
}

Application Task

Reads Temperature and Humidity data. This data logs to USBUART every 1500ms.

void application_task ( void )
{
log_printf( &logger, " Temperature : %.2f\r\n", temperature );
humidity = temphum11_get_humidity( &temphum11 );
log_printf( &logger, " Humidity : %.2f\r\n", humidity );
log_printf( &logger, "-----------------\r\n" );
Delay_ms( 1500 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations

Depending on the development board you are using, you may need 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.
