Ultra-Low Power Microcontroller Selection for Smart Sticker Design

Smart Sticker concept describes a device for products environmental condition data-logging in the supply chain. The device must operate in different conditions, monitor different parameters, and have long battery life. In this paper, we present an analysis and selection of the low-power microcontrollers considered for developing the Smart sticker prototype. The key task in designing the Smart Sticker is to implement low-power, cost-effective and small-footprint components. To choose the appropriate microcontroller several parameters are considered, such as energy consumption in normal operation and deep sleep mode, required features, operating temperature range, price, and dimensions. Larger sized, higher-priced, higher in energy consumption, and feature richer microcontrollers are excluded from our selection. The result of the conducted testing and analysis are discussed, and recommendations are given for the selection of microcontrollers based on the specific Smart Sticker design.
