Hardware

Using a ESP32 with QMC5883L compass module. TBD

Accuracy

Quite accurate, each interval (max to min to max) from the water meter appears to be 32.5ml, this was confirmed over the course of a few days and about 1.6 m³ of water (about 49 thousand intervals).</description>

I think Frontenac would be best, at the very least, they have the most detailed information on their website and they have Kevlar canoes. We pickup the canoes in Frontenac and drive them down to Kingston. Similar to Saugeen, we drive a car back to Frontenac, or leave a car there if we can get…</description>
