Aiming at situation that more and more aging people who have chronic diseases taking medicine for a long time once take by mistake will cause serious problems

put forward a scheme for smart pill box case system which based on EFM32 and GSM. After the signal which high precision sensor output transformed by CS1242 module

the main controller EFM32 read value through UART

and modify the algorithm

exclude the by impact of the noise. And then upload the obtained value by GSM

at the same time

get command
