Five Building Blocks of Self-Powered Wireless Sensor Nodes

摘要

Today, autonomous sensors are in use for a variety of applications. Typically found in smart buildings and factories, these sensing applications include humidity, temperature, and chemical gas monitoring. They are often placed in remote locations where line power is unavailable, so rely heavily on battery power to function, In order to provide dependable operation, batteries have to be changed often, adding to the total cost of ownership. Ownership cost includes expensive labor needed to change the batteries during routine maintenance.
