# Ambient Light Sensor Module

<figure><img src="/files/uvuDsdCnrwqqhMqe47kj" alt=""><figcaption><p>Ambient Light Sensor Module</p></figcaption></figure>

Here is the [datasheet of the ambient light sensor (IN-S32GTLS)](https://www.inolux-corp.com/datasheet/IR/Sensor/Ambient%20Light%20Sensor/IN-S32GTLS_V1.0.pdf) on the module.

<mark style="color:red;">The Ambient Light Sensor Module</mark> is a light-sensitive measurement device suitable for a variety of applications, including educational settings and mobile robotics. It can be used in scenarios where light measurement is required, such as in Braitenberg robots, energy-saving light systems, and automatic brightness adjusting systems. It is an ideal tool for creating interactions connected to environmental changes.

The light measurement is expressed in lux and is processed by a resistance calculation inside the microcontroller.
