Smart tool system, devices, and methods

An external pneumatic tool monitoring device configured to be positioned on an exterior of a pneumatic tool, the external pneumatic tool monitoring device comprising:

• an external pneumatic tool monitoring device housing configured to couple with an exterior surface of the pneumatic tool at a plurality of attachment points on the exterior surface of the pneumatic tool;
• one or more controllers positioned within the external pneumatic tool monitoring device housing and configured to transition the external pneumatic tool monitoring device from a hibernate mode to a wake mode in response to detecting operation of the pneumatic tool;
• one or more sensors including a pressure sensor and an accelerometer positioned within the external pneumatic tool monitoring device housing and configured to measure properties of the pneumatic tool over a period of time, the properties comprising pressure and acceleration of the pneumatic tool at an attachment point in the plurality of attachment points, wherein at least one of the one or more sensors is activated when the external pneumatic tool monitoring device is in the wake mode and deactivated when the external pneumatic tool monitoring device is in the hibernate mode;
• a communication interface positioned within the external pneumatic tool monitoring device housing and configured to transmit data from the external pneumatic tool monitoring device to one or more external devices, the transmitted data being generated based at least in part on the measured one or more properties of the pneumatic tool over the period of time;
• and
• a power source positioned within the external pneumatic tool monitoring device housing and configured to provide power to the one or more sensors and the communication interface.
