Irrigation that decides on evidence, not habit
Precision Irrigation Automation System — solenoid-controlled irrigation driven by soil moisture, weather, crop stage and plot characteristics rather than a fixed calendar.

How it works
Decisions from data
Scheduling computed from soil moisture, weather conditions, soil type, plot area and crop stage — not from a calendar someone set in March.
Direct valve control
Solenoid valves and pump control actuated automatically, so the irrigation event follows the decision without anyone walking to the field.
Forward scheduling
Forecast-aware planning that defers irrigation ahead of expected rainfall instead of watering into a storm.
Zone by zone
Independent control per zone, because a single holding rarely has uniform soil, slope or crop.
Manual override, always
Full local and remote override. Automation assists the operator; it does not lock them out.
Logged and reviewable
Every decision and actuation recorded, so water use can be audited and the scheduling logic refined over a season.
The problem with calendar irrigation
Most irrigation runs on a schedule set at the start of the season and adjusted by feel. It waters when it rained yesterday. It under-waters during a heat spike. It applies the same volume to a sandy zone and a clay zone.
Water is the scarcest input in most of the geographies we work in, and calendar irrigation wastes a meaningful share of it while still missing the moments that matter.
What automation is actually for
Not removing the farmer. Removing the trips.
The decision — whether this zone needs water today, and how much — is a calculation from measurable inputs. Making it automatically, and acting on it without someone driving to a valve, is where the time and water are saved.
The operator keeps full override, because the system does not know that the harvest crew is in that block this afternoon.
Better together
PIAS reaches its best accuracy paired with an on-site Smart Weather Station, which replaces regional forecast data with conditions measured on the plot itself.

Frequently asked
About PIAS
What crops and farm sizes does PIAS support?
PIAS is crop-agnostic — it's been deployed across horticulture, field crops, nurseries and research plots. Zone-level control scales from sub-acre research blocks to multi-hectare commercial farms; the controller unit stays the same, only the number of valves and sensors changes.
Does PIAS need the APx Smart Weather Station?
It integrates seamlessly with Smart Weather Station, but no — it can run against any upstream weather and soil-moisture feed with a compatible protocol (LoRaWAN, MQTT, REST). The scheduling logic cares about the signal, not the sensor.
Can PIAS override its own decisions?
Yes. Every zone has local and remote manual override. Automation is advisory-plus-actuation; operators can pause, extend or re-direct irrigation at any time. All overrides log alongside automated decisions.
How does PIAS handle power and connectivity in remote fields?
Solar-powered controllers with battery backup for 72+ hours of autonomous operation. Connectivity defaults to LoRaWAN for low-power long range; cellular (4G LTE-M / NB-IoT) is an option where coverage is reliable.
