Telemetry / wired and wireless / Valve control
R2-DX® monitors irrigation on most situations (soil / plant / climate / equipment)
Handles Watermark® sensors and other resistive sensors.
Measurements and monitoring are performed, recorded, transmitted, processed, and dispatched automatically.

Diagnostic features for installer
High sensitivity system: offers best performance in agriculture – typically inside canopy 40cm above ground, sometimes in poor signal areas, or even underground in city landscaping.
Cheapest pre-paid SIM card can be used (sold in supermarket or by internet). Extremely convenient for “dealers”, “advisor” or “users”.
A proven measurement method
Matching the agronomic rules of “a representative spot per field equipped with adequate number of sensors”, used successfully for decades. A field is defined as a unit “plant / soil / irrigation mode”.
The system allows connecting up to 32 sensors, to allow research and precise investigations on many sensors installed on small areas. The system is designed to respect those agronomic measuring rules, allowing consistent advices and irrigation monitoring.
• 6 Watermark® sensors
(3 pairs × 2 depths) + 1 Soil Temp + 1 rain gaugeUsed on 60 cm root systems, for classical sprinkler, pivot, microjet, gun, row irrigation and drip irrigation – without valve control
• 8 Watermark® sensors
(4 different bulbs equipped × 2 depths) + 1 Soil Temp + 1 rain gauge (collecting rain + water from a single drip).Check 4 bulbs when valve control is performed
• 9 Watermark® sensors
(3 trio x 3 depths) 1 Soil Temp + 1 rain gaugeFor classical sprinkler, pivot, microjet, gun, row irrigation / 90 cm root systems
• Wireless network
Several R2-DX stations with their sensors spread over a large area.
Smart control (R2-DX Smart only)
“Smart control” interprets the sensor feedback, follows a weekly irrigation schedule, cancels useless irrigations and operates the corresponding sector latch or permanent solenoid valves.
As a result, R2-DX®-SMART measures, reports and maintains the stability of Drip irrigation bulbs in soil, while water consumption changes continuously with climate / soil / plant conditions. Irrigations are scheduled on a maximum time-framed basis for a given run time (e.g. in drip irrigation: 3 times everyday × 1.5 L per drip). Only useful irrigations happen.
Example:Result in the soil reported continuously by R2-DX®-SMART: stability of tensions in soil shows that the bulbs remain stable.
