IrThermo Click 3.3V is a contactless temperature measurement device that relies on the accurate thermopile sensor chip, which encompasses both the thermopile sensor element and the ASSP. The ASSP - signal conditioning circuitry features 17bit ADC and powerful DSP which allow high degree of accuracy and wide temperature measurement range. The IrThermo Click is equipped with both the 10bit PWM interface and the SMBus/I2C interface.

IrThermo Click 3.3V is a contactless temperature measurement device that relies on the accurate thermopile sensor chip, which encompasses both the thermopile sensor element and the ASSP. The ASSP - signal conditioning circuitry features 17bit ADC and powerful DSP which allow high degree of accuracy and wide temperature measurement range. The IrThermo Click is equipped with both the 10bit PWM interface and the SMBus/I2C interface.
We provide a library for the IrThermo3V3 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for IrThermo3V3 Click driver.
irthermo3v3_cfg_setup
Config Object Initialization function.
void irthermo3v3_cfg_setup ( irthermo3v3_cfg_t *cfg );
irthermo3v3_init
Initialization function.
err_t irthermo3v3_init ( irthermo3v3_t *ctx, irthermo3v3_cfg_t *cfg );
irthermo3v3_get_t_ambient
Reads Temperature ambient from sensor.
float irthermo3v3_get_t_ambient ( irthermo3v3_t* ctx );
irthermo3v3_get_t_object
Reads Temperature object1 from sensor.
float irthermo3v3_get_t_object ( irthermo3v3_t* ctx );
This application collects data from the sensor, and logs the results.
The demo application is composed of two sections :
Initializes IrThermo 3V3 Driver.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
irthermo3v3_cfg_t irthermo3v3_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.

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. UART terminal is available in all MikroElektronika compilers.
