Claim:
1. A blast event recording device comprising: at least one first sensor for measuring a parameter indicative of a blast event; at least one comparator in communication with said at least one first sensor that determines whether said parameter indicative of a blast event measured by said at least one first sensor exceeds a first predetermined threshold; at least one second sensor that measures a blast event parameter, wherein said at least one second sensor has a higher power consumption than said at least one first sensor; a power control providing power to said at least one second sensor only when said first predetermined threshold is exceeded, whereby said at least one second sensor is only consuming power when said first predetermined threshold is exceeded; and, a controller that receives and records said blast event parameter measured by said at least one second sensor; wherein said comparator determines whether said parameter indicative of a blast event further exceeds a second predetermined threshold, and said power control provides power to said controller only when said second predetermined threshold is exceeded.
