Library Description

The library performs IR and temperature measurement. The sensor measures the temperature of the detected object (body) and measures the ambient temperature. For more details, see the documentation.

Key functions :

• void irthermo3_init() - Function for initialization chip 
• float irthermo3_getAmbientTemperature() - Function for reading Ambient temperature
• float irthermo3_getObjectTemperature() - Function for read Object temperature

Example description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Driver init and chip initialization
• Application Task - Reads the ambient temperature and temperature of the object every 400ms.

void applicationTask()
{
 ambientTemp = irthermo3_getAmbientTemperature();
 mikrobus_logWrite(" Ambient temperature : ",_LOG_TEXT);
 FloatToStr(ambientTemp, demoText);
 mikrobus_logWrite(demoText,_LOG_LINE);

 objectTemp = irthermo3_getObjectTemperature();
 mikrobus_logWrite(" Object temperature :",_LOG_TEXT);
 FloatToStr(objectTemp, demoText);
 mikrobus_logWrite(demoText, _LOG_LINE);

 mikrobus_logWrite(" ",_LOG_LINE);
 Delay_ms(1000);
}

Other mikroE Libraries used in the example:

• I2C
• Conversions

Additional notes and information

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.
