Key features

• Completely automatic

• No electricity is needed (no batteries, no solar panels, no computers, and no electronics)

• Smart irrigation controller – the irrigation is controlled by the prevailing weather conditions rather than a program

• Use for gravity feed or pressurised irrigation (water supply pressure at least 10 kPa)

• Use for sprinkler or drip irrigation

• Use for pressure compensating drippers or non pressure compensating drippers

• You can adjust the water usage during the irrigation event by adjusting the control dripper

• You can adjust the irrigation frequency by adjusting the float

• The irrigation frequency and thewater usage rate are directly proportional to the net evaporation rate (evaporation minus rainfall)

• Responds appropriately to an unexpected heat wave

• When it rains, water enters the evaporator and delays the start of the next irrigation

• Uses much less water without affecting the yield

• Simple and low tech and so easy to assemble and fewer things to go wrong

• You can leave your garden unattended for weeks on end
