IoT-Based Weather Monitoring System - Computer Engineering Project Guide
1. Introduction
The IoT-Based Weather Monitoring System is a smart system that uses internet-connected sensors to collect real-time weather data such as temperature, humidity, pressure, and other environmental parameters. This data is then transmitted to the cloud where it can be accessed and analyzed through a web or mobile interface.
2. Objective
