BOX 834 YAOUNDEtimobless2015@gmail.com and manimiergueestelle@gmail.comABSTRACT:Measurement of atmospheric parameters is crucial for weather forecasting, future studies, and understanding climate change. This study explores the use of locally sourced materials such as ARDUINO sensors (to measure temperature and humidity) and a rain gauge using graduated Coca-Cola bottles by our school club named Meteo‒Eau Horizon.On September 24th, 2025, with the assistance of resource persons who were Doctorate students from the University of Yaoundé 1, we built four Arduino sensors and positioned them in four zones within the school premises, collecting temperature and humidity data for eight weeks. This exercise was conducted every Wednesday from 1:30 pm in the four different zones.On October 1st, 2025, students constructed rain gauges and positioned them in their various homes, collecting daily rainfall data in quarters such as Chateau, Bonamoussadi, Melen, Obili, Carousel, Emia, and Mokollo. Data collection started on October 7th, 2025, and ended on November 7th, 2025.Eight different sites were identified, and with the aid of a GPS, a location map was created. Data were analyzed and presented using line graphs (temperature and humidity) and multiple bar charts (rainfall).Findings show that temperature and humidity vary within the school premises. Zone one, close to the weather station, had similar data to the modern weather station. Zones two, three, and four had slightly varied data. Rainfall data revealed variations within Yaoundé, with some quarters recording higher quantities than the station.This research highlights the potential of integrating local and modern techniques for enhanced weather monitoring and contributes to understanding weather monitoring approaches in schools.Keywords: Atmospheric parameters, Arduino sensors, Climate change, Weather monitoring.
