  • 1) One of tutorial links shows a resistor on the geophone. What is it for? Do I need it? If so, what is the resistance required? https://create.arduino.cc/projecthub/team-protocentral/measuring-seismic-activity-using-protocentral-openpressure-702324 2) I purchased the ADS1220 amplifier used in that link and wired it up. Although the signal increases if I shake it, it has this weird look to it, it seems squarish, with lots of 0 values. Anyone know what could be the issue? https://i.imgur.com/hNdHcuM.png 3) The ADC seems to saturate when pick up and shake the geophone gently. Is this normal? Anyone know what could be causing this? 4) Is there a recommended amplifier/ADC I can buy to get a reasonable looking signal?

No public wish lists :(
