Abstract
A sensor node configured to acquire sensor data on one or more properties of a railroad environment, wirelessly transmit data related to the property(ies), and generate sufficient power to operate the sensor node without access to any additional power sources is provided. The sensor node can be deployed as part of a group of sensor nodes, which provide data for use by a railroad system in monitoring and/or controlling the railroad environment. In this manner, various properties of the railroad environment can be monitored without requiring significant wiring to the various sensor nodes.
