Altering the structure of drugs to improve the effectiveness Studying spectral emission lines of distant galaxiesĥ. Monitoring dissolved oxygen content in aquatic ecosystemsĤ. Determining the metabolic structure of a muscleģ. Determining the atomic structure of a sampleĢ. Some of the application areas of Spectroscopy are as follows.ġ. Spectroscopy uses these characteristics to deduce and analyze the composition of a sample. Each type of molecule and atom will reflect, absorb, or emit electromagnetic radiation in its own characteristic way. Spectroscopy is used in physical and analytical chemistry to detect, determine, or quantify the molecular or structural composition of a sample. A plot of the response as a function of wavelength is referred to as a spectrum. The response is usually recorded as a function of radiation wavelength. The basic principle of the spectroscopic technique is to shine a beam of electromagnetic radiation onto a sample of the material and observe how it responds to such a stimulus. The term “ spectroscopy” is a technique that uses radiation to obtain information on the structure and properties of matter. The components purchase link is given below. All the components can be easily purchased from Amazon. So we may need a few components as shown in the table below. To learn more about the Spectroscopy and the spectral Sensor AS7265x, we have to interface the sensor with Arduino. 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. Since this is basic beginners guide for AS7265x, we will learn about the construction, working, internal architecture all other functionalities of the sensor. We will also read the raw data as well as the temperature. In this guide, we will interface Triad Spectroscopy Sensor AS7265x with Arduino Board and perform the basic readings of all 18 channels. 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 simpler terms, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum. 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 one of our previous post, we learnt about about the Color Sensor TCS3200 and a UV Sensor ML8511 which can also measure color frequency. 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. Using the Triad Spectroscopy Sensor AS7265x, we can make our own Spectrophotometer. We can interface AS7265x with Arduino & any other microcontroller. The Triad Spectroscopy Sensor AS7265x from Sparkfun is a powerful optical spectral sensor to study light features.
