Abstract
A wireless end device is provided. For one embodiment, a wireless end device may comprise a sensor integrated with a telemetry device. The wireless end device may monitor the sensor for a predefined condition, and transmit a message to a controller in response to detecting the predefined condition. For one embodiment, the sensor may be a vibration or level switch, and the predefined event may be a switch closure. For another embodiment, a control system is provided comprising a controller and one or more wireless end devices.
