Valve-level insight
The platform reports state and battery for every station – failures surface before crops suffer.
One-drive-two
A single CJS-4G commands two valves – halve the hardware on row crops.
Zero trenching
Solar + 4G means no cable runs across fields.
Fertigation-ready
EC and N-P-K sensor options tie nutrition into the same dashboard.
Frequently asked questions
How many valves can one CJS-4G run?
Two channels (one-drive-two). Chain multiple units on the same IoT project for whole-farm coverage.
What happens after a week of clouds?
The catalog-stated battery holds 30+ days without sun, and the platform alerts you on low charge.
