Library Description

The library includes function for read Temperature and Relative Huminidy data and function for start measurement. The user also has the function for reads HIGH or LOW alarm state.

Key functions:

• uint8_t temphum5_startMeasurement() - Functions for start measurement
• float temphum5_getTemperature(uint8_t tempIn) - Functions for read Temperature data
• float temphum5_getHumidity() - Functions for read Relative Huminidy data

Examples description

The application is composed of the three sections :

• System Initialization - Initializes I2C module and sets PWM and INT pin as INPUT
• Application Initialization - Initialization driver init
• Application Task - (code snippet) - Reads Temperature and Humidity data and this data logs to USBUART every 1 sec.

void applicationTask()
{
    char demoText[ 50 ];
    float Temperature;
    float Humidity;
    
    temphum5_startMeasurement();
    
    Temperature = temphum5_getTemperature(_TEMPHUM5_TEMP_DATA_IN_CELSIUS);
    FloatToStr(Temperature, demoText);
    demoText[ 6 ] = 0;
    mikrobus_logWrite(" Temperature : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite( " C", _LOG_LINE);
    
    Humidity = temphum5_getHumidity();
    FloatToStr(Humidity, demoText);
    demoText[ 6 ] = 0;
    mikrobus_logWrite(" Humidity : ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite( " RH", _LOG_LINE);
    
    mikrobus_logWrite("------------------------", _LOG_LINE);
    Delay_ms( 1000 );
}

• I2C
• UART
• Conversions

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.
