For a couple of cents, couldn't the grinder circuit include a basic 555 timer de-bounce circuit to suppress multiple triggers within, say, 30 minutes? That seems a lot cheaper than an alarm. Alternatively, why doesn't the grinder have a higher minimum triggering flow rate? It seems it's falsely detecting potential solids arrival.
