The IR Sense Click Board™ utilises the AK9750 quantum-type IR sensor. The Click Board™ 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.

The IR Sense Click Board™ 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.
The IR Sense Click Board™ 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.
AK9750 FEATURES
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.
How Does The IR Sense Click Board™ Work?
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 SNIPPET
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.
