Uneven watering between zones
Without zone-level status, one area may continue watering while another receives too little water.
WIRELESS IRRIGATION · ZONE CONTROL
Wireless Irrigation
Wireless Control for Zone Pumps and Valves
Connect pumps, zone valves and field sensors, view irrigation status centrally, and control equipment by schedule or field conditions. The control method depends on valve type, node power, wireless coverage and offline requirements.

On site
Where field irrigation becomes difficult
Manual valve rounds
Distributed valves require staff to travel between control points for each irrigation cycle.
Missed valve operations
Widely separated valves make it harder to confirm that each point was opened and closed as planned.
Decisions based on visual inspection
Visual checks do not provide a consistent soil-moisture measurement for each zone.
Changes in weather and field conditions
Irrigation schedules may need adjustment when temperature, rainfall or soil conditions change.
System workflow
Separate sensing, decisions and valve control
Match the sensing path and valve-control method to the field layout.
- 01
Measure soil conditions
Compatible soil-moisture sensors provide readings through their selected serial or field interface.
- 02
Connect the measurements
A Y201-G carries RS485 / RS232 data over 4G. A separate receiver or interface is needed for a LoRa field link.
- 03
Set the operating rules
A configured platform or local controller applies schedules, thresholds and approved operator actions.
- 04
Switch matched valve circuits
Select the valve controller, relay or contactor arrangement for the required zone control and load.
Y403-11-L provides coordinated contact linkage: an input on any node energizes all linked outputs. Independently controlled zones need a suitable controller and command interface; Y201-G has no built-in LoRa radio.
Monitoring and control
Irrigation operating modes
Schedules, thresholds and group operation depend on the selected controller, field interfaces and project configuration.
Scheduled plans
Run fixed plans such as Monday, Wednesday, and Friday at 06:00 for 40 minutes.
Soil thresholds
Start when moisture drops below the threshold and stop when the target is reached.
Remote grouping
Start or stop the whole farm, or selected zones, from the mobile app.
Alarm linkage
Abnormal flow can trigger valve closure and an app alert for burst pipes or blockage.
Solar-ready operation
Solar and battery power can be evaluated for the field nodes and valve loads. Confirm duty cycle, battery autonomy and maintenance for the site.
Application examples
Match irrigation to the growing area
Irrigation settings and equipment vary by crop, soil conditions and water-delivery method.
Lawn and green space
Scheduled irrigation replaces manual water trucks across large turf areas.
Vegetable farm
High-frequency, low-volume watering with narrow humidity thresholds.
Orchard
Deep soil moisture monitoring connected to drip or micro-spray irrigation.
Greenhouse
Moisture-triggered irrigation with logs for repeatable production records.
Landscape and garden
Remote automated irrigation for maintained landscapes without manual rounds.
Deployment planning
Plan the field installation
Connect soil-moisture points, zone valves, field nodes and a cellular gateway around the field layout.
Map soil-moisture points, valve groups, node power and network coverage before choosing the sensing and control paths.
Y201-G can upload serial sensor readings over 4G. The controller and field interface must support the required independent valve commands or coordinated contact linkage.
Test schedules, thresholds, electrical protection, manual operation and recovery with the selected equipment.

FAQ
Practical answers for farm owners and agricultural project teams.
Can one Y201-G serve an entire farm?
The Y201-G provides the cellular cloud bridge. The final number and placement of Y403-11-L nodes depend on the farm layout, LoRa path, valve groups and site conditions.
How should soil-moisture sensor position be decided?
Position and depth depend on crop root zone, soil profile, irrigation method, sensor model and the monitoring objective. Confirm the placement with the agronomy or project plan instead of applying one depth to each field.
How are off-grid field sites powered?
Solar and battery power can be evaluated where mains power is unavailable. Autonomy depends on node duty cycle, valve or contactor load, weather, battery capacity and maintenance, so the power design must be confirmed per site.
Is the Y403-11-L a pure I/O device?
Y403-11-L is a LoRa Wireless I/O Module and is not the Internet bridge. The field I/O, gateway and uplink roles must be separated when planning the network; the exact channels depend on the selected model.
Can the system connect to existing pumps and solenoid valves?
It can be evaluated when the valve or pump control voltage, current, switching mode, feedback and protection are compatible. A contactor or additional protection may be required; existing pipework does not remove the need for an electrical review.
How long does installation take?
Installation depends on the pipework, valve groups, power and network plan. We confirm the commissioning schedule after reviewing the site.
