# Earthworm Module:
Ewaccel Overview

(last revised 8 June, 2011)

The ewaccel module monitors a ring for TRACEBUF2 messages, assumed to be from sensors on different floors of a building. The sum of the forces for the floors is computed for each sample time and, if it exceeds a specified threshold, an alarm message is written to an output ring.

The primary options are what floors to monitor (identifying the sensor and values for converting its values into forces) and what threshold to use.
