The EKYShock is a stand-alone mechanical shock data logging system. The device measures 3-axis acceleration, temperature, humidity, GPS position, velocity & time. When accelerations exceed a user configurable threshold, data for all measurements is recorded as a single event. Over 3700 individual events are stored in a FIFO memory. Software application allows remote operations including programming, download and data analysis. The EKYShock can be externally powered from a DC or AC source and is equipped with a rechargeable battery backup supply.
