STANDALONE METER FOR MONITORING ULTRAVIOLET RADIATION

Abstract

The invention relates to a self-contained ultraviolet radiation monitoring device configured to record and query solar irradiance levels in the 280 to 360 nanometer range in real time. The system comprises an ultraviolet radiation sensor that generates voltage signals proportional to the radiation intensity, an embedded system module that acquires and transmits these signals every minute via Wi-Fi wireless communication using the MQTT protocol, and a self-contained solar charging system consisting of a solar panel, a charge controller, and a 12-volt AGM battery. The data is received by a single-board computer connected to the electrical grid, which acts as a local server. This server stores the information in a local database and allows its querying through a web application accessible from mobile or desktop devices connected to the same wireless network.The system operates only during the day and automatically shuts down at night. The invention requires no internet connection or subscriptions and allows direct access to the collected information.
