Hydro-power generation for irrigation control

A method of cleaning filter debris in an irrigation conduit, comprising:

• passing fluid flow through a filter in a fluid flow path of the irrigation conduit such that debris may collect on a filter surface of the filter;
• and
• physically contacting a portion of the filter surface with a scrubber surface of a movable portion of a filter cleaner, wherein the filter cleaner comprises a first portion fixed proximate to a location in the fluid flow path of the irrigation conduit containing the filter;
• and
• moving the scrubber surface against the filter surface in response to a change in flow of the fluid flow such that the change in the flow causes the scrubber surface to clean the portion of the filter surface.

A filter health monitor system for use in an irrigation conduit, comprising:

• a filter monitor circuit comprising:
• a first pressure sensor configured to be located proximate an upstream surface of a filter located in a fluid flow path of the irrigation conduit such that fluid flow will pass through the filter and debris may collect on a filter surface, wherein the first pressure sensor is configured to output a first signal corresponding to a first pressure of the fluid flow proximate the upstream surface of the filter;
• a second pressure sensor configured to be located proximate a downstream surface of the filter and to output a second signal corresponding to a second pressure of the fluid flow proximate the downstream surface of the filter;
• and
• a control circuit coupled to the first pressure sensor and the second pressure sensor and configured to determine, based on the first signal and the second signal, a health of the filter.
