Low power design based on seed circulation Supervisory Hand-held device

Food safety becomes more and more important nowadays. Agricultural materials safety such as seed is an important prerequisite for food safety. The seed circulation Supervisory Hand-held device is designed to deal with the problems like market outlets dispersing, manual operation and lack in information etc. Low power design technology brings us smaller size and longer operating time of handheld device. This paper presents a low power hardware design using LTC3577 and LTC2941, and a software power management. The results show that the system power consumption would be greatly reduced by the strategy this paper use.
