What type of technology is primarily used in sensor networks for minimal energy consumption?

In sensor networks, minimal energy consumption is critical for extending the operational life of devices deployed in environments where frequent battery replacement is impractical. Mica Motes represent a class of devices specifically designed for this purpose. They are lightweight, low-power wireless computing devices optimized for sensor network applications.

Mica Motes are equipped with microcontrollers that operate at low power levels, making them ideal for long-term remote sensing tasks. Additionally, these devices are designed to efficiently collect, process, and transmit data while using the least amount of energy possible, which is essential in scenarios where they are powered by batteries or energy-harvesting techniques.

In contrast, smartphones, laptops, and tablets are general-purpose computing devices that do not prioritize low energy consumption to the same extent as Mica Motes. While they have power-saving features, they typically consume significantly more energy and are not specifically built for the energy-constrained environments found in sensor networks.
