EchoPro SMA Accelerograph
The EchoPro SMA was an all-in-one strong motion accelerograph combining a MEMS accelerometer with an onboard recorder. It has been discontinued and replaced by the Gecko SMA, which carries over its core design.

Overview
In detail
How it works
EchoPro SMA combined a MEMS accelerometer with the reliability and simplicity of an all-in-one sensor-and-recorder unit, measuring motion in three dimensions (typically North-South, East-West and Up-Down). Continuous data was stored on a removable USB flash drive in one-minute files, organised into year/month/day/hour folders for easy browsing on any PC.
Installation
The unit was supplied on a mounting plate, bolted down and levelled using threaded feet, for mounting on the ground or a wall; a North indicator was included for orientation.
Connectivity
An optional LCD and keypad allowed configuration without a PC. Ethernet connectivity let the unit send data files to a remote PC, and data telemetry gave access to the eqAlert service, which sends SMS alerts when the SMA detects abnormal activity.
