<span style=”font-size:18px;”><span style=”font-family:Arial,Helvetica,sans-serif;”><strong>4-pin interface which are: AO, DO, GND and VCC:</strong></span></span></p>

<ol>
<li>
<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”><strong>AO </strong>is an analog output pin, the analog voltage will be high when there is no obstacle or infrared reflection. The voltage will gradually decrease when the infrared receive it high.</span></span></p>
</li>
<li>
<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”><strong>DO </strong>is a digital output pin from the sensor module, please connect to any digital input on your microcontroller. Will output logic LOW when object is detection</span></span></p>
</li>
<li>
<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”><strong>GND </strong>is where you connect to your controller ground or 0V</span></span></p>
</li>
<li>
<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”><strong>VCC </strong>is the +ve supply, connect to either +3.3V or +5V</span></span></p>
</li>
