The Triad Spectroscopy Sensor AS7265x from Sparkfun is a powerful optical spectral sensor to study light features. We can interface AS7265x with Arduino & any other microcontroller. Using the Triad Spectroscopy Sensor AS7265x, we can make our own Spectrophotometer. The sensor has the ability to measure and characterize how various types of materials absorb or reflect 18 different frequencies of light ranging from 410nm to 940nm.

The term Spectroscopy means the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. In simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. By performing this dissection and analysis of an object’s light, the researcher can infer the physical properties of that object such as temperature, mass, luminosity, and composition.

In this guide, we will interface Triad Spectroscopy Sensor AS7265x with Arduino Board and perform the basic readings of all 18 channels. We will also read the raw data as well as the temperature. Since this is basic beginners guide for AS7265x, we will learn about the construction, working, internal architecture all other functionalities of the sensor. The sensor is made by the combination of visible, UV & IR LEDs or 3 different sensors like AS72651 (UV), AS72652 (VIS), and AS72653 (NIR) so it is called Triad Spectroscopy.

Good to see you back after a long time Shraddha.

This is really high-quality stuff! I really enjoy watching these videos. I liked seeing how you used the Triad Spectroscopy Sensor. Anyway thank_you.

Using this same board and following the instructions given here. At 1st board works fine got reading for basic reading example, then for another examples serial monitor displaying the message "board is not connected check the wiring.... Freezing. "

Thank you so much for this video ❤️ I was searching for this video for so long. Thank you shradha for making a video on this. 🤩👍

[flaviadiscala]

can you do a video on AS7261, that is a similar sensor but does not work with this library.

[rabz]

am i suppose to wait some times before it takes measurement? it only says AS7265x Spectral Triad Example

[aneeshava]

Hi, Nicely explained. I have a doubt when you read the sensor data, What is the Data you're getting? Is it the intensity values of the all the Sensor channel? or something else ? Can you please reply to this comment.

[romelabelsolisflores]

I have a question, how far should the object be from the sensor and what is the maximum size that can be measured?

[srihari-vvsq]

If i want to access uart connection, shout i cut the track between three solder header in i2c marked in pcb?

[priyankashah]

It is very urgent can you please tell if this sensor can tell the intensity of the wavelengths present in the natural light? If I use this sensor to measure the intensity of red or blue light within the natural light will it give me proper value?

[DARKVEEMON]

Great video, but once I get the result of the 18 channels what do I do? I mean, when I search for the visible spectre of some materials I don't see all the 18 frequencies

[.กษาปณ์เม้ยนรธา]

But my code has sensor.begin() = flase How can i fix it(i use esp32 wroom)

[subhamdas]

How to get material of a food on the based of the 18 channel readings like fat sugar carbohydrates etc

[SaySanVicente]

does this sensor can be program in detecting plastic?

[ahmedboubaker]

Thanks! Your video was very helpful :)

[marcosgonzalezrodriguez]

Please, more tutorials about this sensor! ;)

[Thewhearts]

Hello,

I want to use this sensor. How can i learn detailed all?

[thahir]

Does it measures the absorption spectrum of liquids?

[joancenteno]

Can I ask sir if this can detect the NPK content of Plant leaves?

[ivymimsybaltar]

Hi! Did you solder the jumper to sensor? im using sparkfun human presence sensor for my thesis
