Development of an ESP-32 Microcontroller Based Weather Reporting Device

Abstract

This study presents a novel approach to incorporating technology into an intelligent weather station. In recent years, the nation has experienced a decline in agricultural activities due to the change in climate causing lot of danger in the farm output; this enables the weather forecaster to actually prescribe disaster by employing the use of temperature, humidity and light sensors which senses the temperature and humidity in the atmosphere. A tipping bucket is used to measure the amount of rainfall with an ESP-32 microcontroller which displays results through a Liquid Crystal Display (LCD) and then send it to the registered number and at the same time is been sent to cloud for easy retrieval purpose using the internet which can be retrieved from any location. This system is designed primarily for use in the school meteorological stations, it is also applicable in various weather stations. The primary goal is to create a low-cost intelligent system for storing data obtained by measuring various physical parameters in the atmosphere, such as temperature, humidity, and rainfall. An ESP-32 is used as the technology for storing measured data; it is an advanced and efficient solution for connection to the Internet. The intelligent weather station system is built around the following steps: direct environmental sensing, data measurement and storage, and allowing users to access the results through the cloud. The system is built around a collection of embedded sensors, and a microcontroller serving as the system's core and server, and wireless internet communication protocol. The results were sent to the cloud, where they are displayed in a tabular and graphical format; these results can be retrieved from the cloud into an excel file.
