Design and Simulation of a Microcontroller Based Weather Station

Abstract

The motivation for this work is centred on the prevailing shortage of weather-related data in Nigeria. The evidence of this fact could be seen in poor weather forecasting in the country, poor response to weather-related natural disasters because of lack of foreknowledge, and unnecessary disruption of flights and flood disasters that destroy lives and properties. This is as a result of the unavailability of a network of weather stations dedicated to national weather service and partly due to the high cost of imported weather stations. This work aims to solve the problem of unavailable weather stations due to their cost and complex technology. The block approach was used in the designing of the system to simply the realization of the objectives. The system was designed to comprise data sensors, microcontroller and display sections. The system was simulated in Proteus 8. Simulation environment. Results from the simulation show that the speed is between 1.8 km/hr. and 117.3Km/hr. Temperature and humidity range depended on the sensor used, in this case, the DHT11.
