Development Of Small Scale Weather Station

The developed system is an Arduino-based Small scale Weather Station that monitors the following parameters Temperature, Humidity, Atmospheric Pressure, Wind speed, and Altitude. The system is divided into two modules, the Weather Station module and the Display module The Weather Station module uses a BME280 module to measure the Temperature, Humidity. Atmospheric Pressure, and Altitude. An anemometer that has an output voltage measures the wind speed. The Display module uses an l6x2 and a 20x4 LCD to display the readings The parameter readings are transmitted from the Weather Station module and received by the Display module using the nrf24lo1 RF module. A set of tests were conducted at PAGASA for the accuracy of the readings The results show that the readings from PAGASA and the developed Weather Station are almost just the same. Another test was conducted to test the Wind speed sensor. The three levels of speed of an electric fan are used to test the sensitivity of the Wind Speed sensor. The results show that the Wind speed sensor is capable of detecting changes in speed quickly. Furthermore, the system was left operating for 24 hours to determine the capability of the Weather Station module to transmit and the Display module to display the readings without overheating The results show that both the Weather Station module and Display module do not overheat with the help of the DC-DC Voltage converter.
