Zusammenfassung:	Systems and methods for determining well conditions below a suspension tool installed in a well so that it can be determined whether the suspension tool can safely be removed or unsealed. The suspension tool has a simple sensor which is normally unpowered, but receives power when engaged by a shifting tool to enable the sensor to measure well conditions below the suspension tool and to communicate this information back to the shifting tool, which is coupled to equipment at the surface of the well by a digital slickline or similar means. The information provided by the sensor enables the operators of the well to determine whether it is safe to proceed with a procedure to remove or unseal the suspension tool.
