Testing the GeoMCU Hardware
Tools Needed
Individual PCB Testing
Power Supplies Check
Flash Firmware
Follow the instructions for Flashing to the PCB to get the firmware running on the sensor board.
Gain Checking
Note
- For a quick check if the board is correctly collecting vibrations:
connect a geophone to the board
- shake the geophone or tap on it while monitoring any of:
the MQTT data (which requires the MQTT Broker and the on-board ADC to work)
the wired output (requires an oscilloscope)
the output from
adc dump(which just relies on a serial power and the on-board ADC)
It should be fairly obvious if the geophone’s signal is being measured or not since it should swing wildly between its maximum and minimum values while the geohpone is shaken.
