Ultra low power device to track environmental sensitive items in transit

Abstract

Environmental parameters such as temperature, humidity, vibration, light intensity, radiation etc. are tightly coupled with various valuable items in transit for product quality and recommended environmental conditions. After the items are dispatched from warehouse and are moving towards destination, these parameters are either not maintained or poorly maintained. Therefore, a portable, low cost embedded device is required to continuously monitor and log the environmental sensitive parameter of the item in transit. This device is configurable by user and will generate alert signals (visual/audio) on certain condition like any violation, device starts/restarts etc. when the item reaches the destination, the data logged by the device can be read for analysis. This paper discusses the design challenges and development processes with respect to a target application for a low power data logger.
