Design Presentation of a Solar Powered Microcontroller-Based Weather Station for the Acquisition of Atmospheric Parameters

Abstract

Accessing real time weather information is still a challenge to atmospheric researchers. This work developed a solar powered Arduino microcontroller weather station that will measure atmospheric temperature, relative humidity, pressure and wind speed and wind direction using appropriate meteorological sensors such as DHT22 sensors for atmospheric temperature and humidity measurement, BMP180 sensors for pressure measurement, a three cup anemometer with reed switch sensor for wind speed measurement and a wind vane with a variable resistor for wind direction measurement An Arduino Atmega 2560 microcontroller processes the output of the sensors, transfer them to the LCD for display and also transmit it to the Wi-Fi module which uploads the data to an online server to enable out-of-site end users to access the measured weather information.
