An outdoor multi-channel phytosensing system designed for environmental monitoring and real-time plant physiology tracking. Built with IP65-rated weatherproof enclosures, the system supports both wired (Ethernet with Power over Ethernet) and wireless (dual-band 2.4/5 GHz Wi-Fi via Silex DS700AC modules) data transmission. It features the same sensor suite as our indoor solutions—such as AI Biolab—and includes 2 m sensor cables alongside a two-segment power line extending up to 23 m. Requires a 12 V DC power supply. The system is designed for AI-based data analysis, stress monitoring and prediction.
