We present the successful development of an Ultraviolet (UV) index monitoring device for determining the daily exposure of an individual to sunlight. The core of the monitor is the calibrated measurement of the UV ray’s incident on the UV nano sensor that was fabricated by self-assembling the ZnO nanoparticle aerosols on a glass substrate featuring platinum interdigitated electrodes. Using Bluetooth low energy 5.0 communication system, the device was connected to the companion mobile application named “UV Index Monitor”. The UV index level varies from 1 to 10, where 1 stand for safe UV radiation and 10 stands for extremely harmful UV exposure. The alert messages will be displayed on the companion application to communicate with the end-users to manage their exposure to UV rays. The device is designed in a wearable watch frame with the dimensions of 5.0 × 3.0 × 2.0 cm and is powered by a 3.7 V rechargeable battery. The UV index data stored in the mobile application can be shared through emails or other platforms for storage.
