摘要： A wireless sensor and actuator network includes a number of wireless nodes, each of which may be connected to any one or combination of analog sensors, digital sensors, and actuators, and is powered by an autonomous power supply such as a battery or solar panel. Since autonomous power sources may not have sufficient voltage for powering many types of analog sensors, digital sensors, and actuators, power management techniques are used in the node and in the autonomous power supply as needed to enable effective and long life operation of the node and connected devices. These power management techniques include the use of a low impedance energy reservoir and a variable voltage boost converter whose output voltage magnitude, duration, and operating times are software configurable and controllable. The power management techniques are particularly useful for operating a wide range of different types of sensors and actuators.
