    Design and construction of a low cost air temperature and pressure data logging equipment using raspberry pi
    (2018) Otunla T.A.; Ukaegbu S.C.; Nympas E.F.
    This paper describes the design and construction of a hnv cost air temperature and pressure data-logging equipment using raspberry pi. The equipment is designed to perform automatic measurements of air temperature and atmospheric pressure and sendthe measured values to the Raspberry pi for togging. Raspberry pi logs the data on a comma-separated value (CSV) file format as wed as store the data for records. The equipment was tested and validated against a standard atmospheric weather observatory. The results indicated a good agreement with coefficient of determination of R~ = 0.83, slope = 0.7, mean bias error, MBE—0.77'C, and root mean squared error R\1SE=I.53"C. The equipment can be further improved to accommodate more sensors and provide data from remote locations.
