Abstract: Aiming at solving the problems of complicated storage and big power consumption, the implementation scheme of portable temperaturehumidity recorder based on SD card was proposed. The realization of integrated design was illustrated in detail. At last, power consumption of the system was estimated and tested. In the system, SD card was applied to store the data, which is convenient for PC processing. The results indicate that the scheme is simpler, cheaper and lower power consumption.
Key words: SD card; temperaturehumidity; recorder
