Development Of UV monitoring system using metal oxide based sensor

The development of ultraviolet (UV) monitoring system using metal oxide-based sensor has been experimented throughout the project. The metal oxide-based sensor used is the fabricated titanium dioxide nanorod arrays. The sensor is a self-powered UV photosensor that can generate a certain amount of voltage when the illumination of UV radiation exists on the surface of the sensor. Furthermore, the fabricated UV photosensor is designed based on photoelectrochemical (PEC) structure. The performance of the sensor has been experimented by manipulating the quantity of the thin film layer deposited on the surface of the sensor that is used as spacer and applying two different electrolytes that is the solution of salt water (Na2SO4) and mineral water in order to observe the generated output voltage with respect to the distance of UV source to the TiO2 UV photo sensor. Moreover, an Arduino board has been used for monitoring the amount of voltage generated from the photo sensor. The TiO2 UV photo sensor generated the voltage up to 0.3V with standard UV lamp that produces UV radiation wavelength of 365-400nm for a single layer of thin film, electrolytes of Na2SO4 and 5 cm distance of UV lamp from the sensor. Further experiments offer some beneficial results with respect to its properties, that leads to the basis of theoretical and experimental for better understanding of fundamental physics and extensive applications of titanium dioxide (TiO2) related structure

Development of data acquisition system for mobile ultraviolet (uv) monitoring device

In this age of modernization, smart or self-sufficient frameworks in all domains of work are becoming increasingly important as innovation advances. This involves improving data collecting for UV monitoring system using metal oxide sensors, an underdeveloped market niche. The Data Acquisition (DAQ) system available at the moment is antiquated and frustrating. This project aims to establish a framework for acquiring information about UV monitoring devices using metal oxide sensors. Metal oxide-based sensor uses titanium dioxide nanorod arrays (TNAs). Self-powered UV photosensor creates electricity when exposed to UV light. UV photosensors are photoelectrochemical (PEC). Monitoring the sensor's real-time output voltage in relation to UV intensity evaluates the data acquisition system's performance. A Raspberry Pi is used to evaluate the data security architecture for the CytronUNO development board. The sensor's data gathering system detected the current produced and stamped the date and time on it. This paper discusses trait formation and experimental data
