This thesis presents the successful development of an Ultraviolet (UV) index monitor for determining daily exposure of an individual under Sunlight. The core measurement of the UV index of the device is the calibration of the effect of incident sun rays on the UV nano sensor. The nano sensor is made of ZnO nanoparticles with an average particle size of 15 nm. It has been fabricated in the laboratory by flame spray pyrolysis fabrication technology which is based on the deposition and self-assembly of ultrafine nanoparticles on a water-cooled substrate. The UV nano sensor is fabricated on glass substrate with a dimension of 10 x 6 x 0.75 mm, featuring platinum interdigitated electrode. The device connects through Bluetooth low energy 5.0 communication to mobile application known as “UV Index Monitor”. The calculation of the UV index varies from a range of 1-10, where 1 stand for safe UV radiation and 10 stands for harmful exposure of UV. The mobile application connected to the device display alert messages to end users like, “You are safe”, “UV protection required” etc varying the range of UV in between 1 to 10. The device is designed in wearable watch frame structure. The device measurements are 5 cm in length, 3 cm in width and 2 cm in thickness. The power source of the device is 3.7 V rechargeable battery. The UV index data from the mobile application comes with sharing through emails or other platforms for data storage. These data can be further used for individuals’ medical health records.
