Modern seismology requires continuous recording of the earth’s movements, and the Gecko is always on and continuously storing data to its removable SD card. From June 2018, the Gecko now has the option of 4 channels, perfect for a triaxial geophone plus microphone for vibration and blast compliance monitoring. Continuous data is can also be telemetered to a remote computer via wireless cellular modem or Ethernet. Using around 1W of power (with passive sensors) means you can record for over a month using a car battery, or indefinitely with a small solar panel and battery.
The Gecko uses the latest 32-bit Analogue to Digital Converter (ADC) chips to maximise the range amplitudes that can be recorded – the ratio of the largest to the smallest recordable signal is a factor of almost 8 million to 1.
