1. What does the Solar Light Sensor control?
2. Is it compatible with all Link4 systems?
It’s specifically designed to enhance Link4 systems.
3. How accurate is the light detection?
4. Is installation complicated?
5. How does real-time light data influence irrigation and CO₂ scheduling?
The sensor provides live light intensity data that the controller uses to adjust irrigation cycles and CO₂ dosing for optimal plant growth.
6. Can this sensor directly control curtain movement, or does it work only with Pearl systems?
It does not control equipment directly. It must be connected to a Pearl or other controller, which will then automatically adjust curtains.
7. What is the recommended placement for optimal accuracy inside or outside the greenhouse?
Placement depends on use outside for sunlight intensity measurement or inside at the crop level for canopy light monitoring.
