3D-Printed Spectrophotometer for Determination of Formaldehyde in Fresh Seafood

3D-Printed Spectrophotometer for Determination of Formaldehyde in Fresh Seafood

Abstract

This research focuses on the development of a 3D-printed spectrophotometer. The device was designed using AutoCAD, ensuring durability, low cost, and portability. It is intended for measuring the amount of formaldehyde in fresh seafood.

Objective

เทคนิคในการตรวจวัดความเข้มข้นฟอร์มาลดีไฮด์ในอาหารทะเลสด เช่น UV-Vis Spectrophotometry เป็นเทคนิคที่ใช้วัดค่าการดูดกลืนแสงของสารและใช้ในการวิเคราะห์ความเข้มข้นของสารในสารละลาย ข้อจำกัดของเทคนิคนี้คือราคาแพง และไม่สะดวกในการใช้งานภาคสนาม จึงมีการพัตนาและสร้างสเปกโตรโฟโตมิเตอร์แบบพิมพ์ 3 มิติ เพื่อตรวจวัดความเข้มข้นฟอร์มาลดีไฮด์ในอาหารทะเลสด ซึ่งมีความสำคัญในการลดต้นทุน พกพาสะดวก และใช้งานง่ายในภาคสนาม

The Development of Hand Gesture Recognition for Controlling Electronic Devices

This research will begin with a review of literature and related studies to examine existing technologies and methods for hand gesture recognition and their applications in controlling electronic devices such as drones, robots, and gaming systems. Subsequently, a hand gesture recognition system will be designed and developed using machine learning and computer vision techniques, with a focus on creating an algorithm that operates quickly and accurately, making it suitable for real-time control. The developed system will be tested and refined using various simulated scenarios to evaluate its efficiency and accuracy in diverse environments. Additionally, a user-friendly interface will be developed to ensure accessibility for all user groups. The research will also incorporate qualitative studies to gather feedback from both novice users and experts, which will contribute to further system improvements, ensuring it effectively meets user needs. Ultimately, the findings of this research will lead to the development of a functional prototype for gesture-based control, which can be applied in industries and entertainment. This will contribute to advancements in innovation and new technologies in the future.
