It uses Arduino microcontroller which controls the data acquisition system and trigger system to initiate the seismic data acquisition. A user-friendly application was designed using LabVIEW to monitor the seismic waveforms on a personal computer. The cost of the seismograph was as low as 70 US dollars.
