Water studies

our custom water depth sensor. It uses a pressure gauge at the bottom and an atmospheric one next to the controller at the top of the pole. This allows for compensation of the varying atmospheric pressure.

lochan node

This shows a node measuring water depth of the lochan/pond and rainfall. This is the same water depth sensor with two pressure sensors – one for atmospheric and the other in the water. An AVR processor and amplifiers process the signals, which are read by the node.
