I am currently sourcing voltage waveform monitor and data logger.
The data logger should be standalone (not connected to PC) and low consumption as it would be driven by solar charger and batteries only.
It would capture voltage input and only capture by triggering (above a certain threshold in voltage level) with pre-trigger samples. And hopefully the captures are saved in individual files (eg, csv, excel).
Central server would then poll the logger periodically to see if any new triggers occur.
Thanks in advance for your valuable suggestion?
