The Smart Solenoid Irrigation Controller transforms any non-latching solenoid into a smart irrigation controller - it's amazing that such a simple device can achieve all of the 12 key features listed.
Key features of the Smart Solenoid Irrigation Controller:
-
Completely automatic
-
No electricity is needed (no batteries, no solar panels, no computers, and no electronics)
-
You can adjust the water usage by adjusting the control dripper
-
You can adjust the irrigation frequency by changing the evaporator
-
The irrigation frequency and the water usage are directly proportional to the net evaporation rate (that is, evaporation minus rainfall
-
Responds appropriately when there is an unexpected heat wave
-
When it rains, water enters the evaporator and delays the start of the next irrigation
-
Water usage is independent of the water supply pressure
-
Uses much less water without affecting the yield
-
It is incredibly simple and low tech and so there are fewer things to go wrong
-
Provided you have a continuous water supply, you can leave your irrigation application unattended for weeks on end
-
Can be used for any size irrigation application provided that the solenoid valve has a large enough flow rate.
Water slowly evaporates from the evaporator until the weight of the water in the evaporator is light enough for the magnet to fall from the high position to the low position.
When the magnet falls from the high position to the low position, the valve opens and the irrigation starts.
When the magnet rises from the low position to the high position, the valve closes and the irrigation stops
During the irrigation, the control dripper drips water into the evaporator until the weight of the water in the evaporator is heavy enough for the magnet to rise from the low position to the high position.
-
The Smart Solenoid Irrigation Controller can be used for sprinkler irrigation as well as drip irrigation.
-
The Smart Solenoid Irrigation Controller can be purchased online from the Measured Irrigation Shop.
-
Detailed instructions for assembling and using the Smart Solenoid Irrigation Controller are in the
Unpowered Measured Irrigation Training Manual for Smallholders.
