Abstract

To obtain accurate weather information is one at the concerns of the people who desire to study atmospheric conditions. In this study, an automated weather station for monitoring temperature, humidity and pressure was constructed. The measured weather parameters were stored into a remote computer via Short Message Service (SMS). The readings were also stored in a database that can be accessed via interim. Moreover, a solar radiation shield for the sensors was constructed for the actual data gathering of the system. The sensors were calibrated by comparing the measurements to other calibrated devices. Hourly values of temperature, humidity and pressure were compared to the reading gathered at UPLB National Agrometeorology Station (NAS). The results showed that the constructed system is comparable to the existing automated data logging system of NAS with an average percent difference of 2.36% for temperature. 4.20% for humidity and 0.03% for pressure.
