Built-In Sensing Capabilities

In addition to the sensor module, the energy-harvesting node has further sensing capabilities. The CC2430 has a built-in temperature sensor that can be used to mea­sure the ambient temperature around the microprocessor. Further sensing abilities are provided by virtue of the energy-harvesting modules that have been attached. For example, a variation in the output level from the solar module may indicate the passing of something over the node, causing a shadow to fall on the solar module. Likewise, an increase in the vibration level measured by examining the instanta­neous power output of the vibration generator may indicate that the structure to which it is attached is under a greater load, for instance, due to the travel of people or vehicles.
