The development and implementation of automated system to monitor the temperature, humidity, and location of a vaccine carrier in real-time are presented in this paper. All the collected data are sent via SMS and also stored on an SD card to prevent the loss of any data. The weak power infrastructure is one of the challenges in the developing countries which brings into consideration the overall power management and power saving modes of the carrier. The monitoring system and vaccine carrier have been powered from the same source: by either using the vehicle battery or portable batteries. The current consumption of the individual components has been reduced up to 92% and the overall current consumption of the system has been reduced by 8%. Being able to monitor the vaccine storage conditions and the carrier location remotely in real-time, and maintaining low power consumption at the same time, would allow to reduce the vaccine wastage rates and can be very effective in increasing the vaccine outreach in developing and undeveloped countries.
