Systems, devices, and methods for smart sensors/monitors and for a smart asset tag solution for tracking assets along the distribution cycle. These solutions are an extension of using various radio frequency technologies to locate the whereabouts of goods/assets with the use of additional sensors to provide granular knowledge about the asset above and beyond location. The technology can differentiate when the asset is being transported, stationary, or other inspection points along the distribution cycle of the cargo. Other applications of smart sensors, monitors, systems, devices and methods can be used to monitor fluid-leak detection or fluid-level detection from an electro-mechanical device, such as water pump, as well as fluid/water such as from a water pump, and for measuring and monitoring condensation levels in a pan under an HVAC system, and the like.
