Abstract
A flexible array of sensor pairs are used to monitor lubricant condition in an oiler carrying lubricant. The array of sensor pairs are placed adjacent a reservoir and detect the fluid level in the reservoir. The sensor pairs are coupled a chassis and transmit data through communications components which transmit the data to an accessible site for aggregation, monitoring, and alarm features. A recharging system for providing power to the sensors by harvesting light, thermal, or kinetic energy produced by the oiler.
