IR Sense click carries the AK9750 quantum-type IR sensor. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over I2C interface, with additional functionality provided by the INT pin on the mikroBUS™ line.
IR Sense cilck detects the temperature of objects and people in motion. It can also detect a human body that remains still. So, it distinguishes heat regardless of the fact whether or not an object is moving.
The AK9750 is an ultra-low power and compact infrared-ray (IR) sensor module. It is composed of four quantum IR sensors and an integrated circuit (IC) for characteristic compensation.
An integral analog-to-digital converter provides 16-bits data outputs. Additional integrated features include a field of view limiter and an optical filter.
The IR sensors are arranged as shown. Each sensor detects the diagonal area, as indicated in the image below:
The observable area of the four sensors is as you see it on the silk of the IR Sense click board™.

Code examples for IR Sense click, written for MikroElektronika hardware and compilers are available on Libstock.
The following code snippet shows the main loop of the IR Sense click example, which reads data every few second and then displays it via UART.
01 while( 1 ) 02 { 03 Delay_ms (5000); 04 05 06 IRGRID2_readAll (readData); 07 08 //Upper area sensor value 09 UART2_Write_Text ("rn "); 10 tempValue = readData [5] + ( readData [6] << 8 ); 11 IntToStr (tempValue, uartText); 12 UART2_Write_Text (uartText); 13 14 //Left area sensor value 15 UART2_Write_Text ("rn"); 16 tempValue = readData [3] + ( readData [4] << 8 ); 17 IntToStr (tempValue, uartText); 18 UART2_Write_Text (uartText); 19 //Right area sensor value 20 UART2_Write_Text (" "); 21 tempValue = readData [7] + ( readData [8] << 8 ); 22 IntToStr (tempValue, uartText); 23 UART2_Write_Text (uartText); 24 25 //Lower area sensor value 26 UART2_Write_Text ("rn "); 27 tempValue = readData [1] + ( readData [2] << 8 ); 28 IntToStr (tempValue, uartText); 29 UART2_Write_Text (uartText); 30 UART2_Write_Text ("rn-------------"); 31 }
