1. An apparatus comprising:

  • a transceiver configured to receive an equipment identification (ID) code, an operator ID code, and RPM data from an equipment data sensor located on a piece of outdoor power equipment located remotely from the apparatus, the equipment data sensor being in communication with an RPM sensor affixed to the outdoor power equipment, the RPM sensor being configured capture the RPM data by sensing revolutions per minute of a motor shaft of the outdoor power equipment or sensing electromagnetic waves generated by components of the outdoor power equipment that vary with revolution per minute of an engine of the outdoor power equipment, the RPM data being sampled throughout a period of operation of the piece of outdoor power equipment, wherein the operator ID code is sampled by a short range transceiver associated with the equipment data sensor and the RPM data comprises RPM values of a rotating component of the piece of outdoor power equipment;

    a memory having one or more parameters stored therein as a function of RPM determined through testing of a particular model of equipment or type of equipment;

    a processing device communicably coupled to the transceiver and the memory, wherein the processing device is configured to;

    generate a RPM histogram for a particular operator and/or for a particular piece of outdoor power equipment based on the RPM data,determine a total parameter value or an average parameter value over the period of operation using the RPM histogram and the function,determine additional information about the particular operator, the particular piece of outdoor power equipment, and/or the period of operation, wherein the additional information comprises information about skill, experience, performance, exposure, or safety of an operator associated with the operator ID code,generate an output based at least partially on the additional information determined about the particular operator, the particular piece of equipment, and/or the period of operation, and the total parameter value or the average parameter value; and

    a network interface communicably coupled to the processing device and configured to;

    cause the output to be transmitted to a client computing system or the piece of outdoor power equipment and displayed on a user interface, wherein the output comprises a data chart or an alert.
