Description
The standard LCD and keypad offers full configuration without the need for a PC in the field. The Gecko SMA draws around 1W of power, so a lead-acid battery of similar size to a car battery will provide about a month of backup power. All Gecko models have dual alarm outputs, and external Ethernet, WiFi, or cellular modem modules are available, allowing you to stream data to a remote PC running our free software, Streams. It will archive and display realtime data on screen, can be viewed remotely via the web, and can also send out email alerts based on user set thresholds.
The low cost Gecko SMA uses MEMS technology accelerometers that are designed to detect large levels of ground motion that may cause structural damage. A magnitude 2.0 earthquake at 100km range might not be visible on a MEMS accelerometer, but with full scale ranges ±2g, ±5g, ±10g and higher available you are certain to detect larger or nearby events. Although the Gecko SMA-HR is over 300 times more sensitive than the SMA, the SMA is only slightly noisier than a standard 4.5Hz geophone but with a much greater full scale range, so the SMA is great for near-field blast monitoring.
@seislologist Our seismographs are not designed to operate for indefinite periods under deep water, but some models will survive being flooded for a decent period of time
