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. The Gecko uses the latest 32-bit Analogue to Digital Converter (ADC) chips to maximise the range of amplitudes that can be recorded – the ratio of the largest to the smallest recordable signal is a factor of almost 8 million to 1.The Gecko has 4 channels, perfect for a triaxial geophone plus microphone for vibration and blast compliance monitoring. Continuous data is captured continuously at 50 to 4000 samples per second, covering a broad band of frequencies from the longest period seismometers to geophones, microphones, and accelerometers with up to 1.6kHz flat frequency response.
Data can also be telemetered to a remote computer via cellular modem or Ethernet/WiFi adaptor. The Gecko recorder uses under 1W of power (with passive sensors) so you can record for over a month using a car battery, or indefinitely with a small solar panel and small battery backup.
