# Title: IR Sense Click Board™


## Description: 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™.

- full_description: <p>The<strong> IR Sense Click Board™</strong> 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.</p>

<p>The <strong>IR Sense Click Board™</strong> 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.</p>

<h3>AK9750 FEATURES</h3>

<p>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.</p>

<p>An integral analog-to-digital converter provides 16-bits data outputs. Additional integrated features include a field of view limiter and an optical filter.</p>

<h3>How Does The IR Sense Click Board™ Work?</h3>

<p>The IR sensors are arranged as shown. Each sensor detects the diagonal area, as indicated in the image below:<br />
