Nexus LITE - the nerve centre of next-generation agriculture - is an advanced IoT solution for agriculture, tailored for both greenhouses and plant factories, enabling seamless control and monitoring of your grow environment.
Sensor suite
Designed for the era of Industry 4.0, Nexus Pro integrates a comprehensive suite of precision sensors to monitor parameters such as temperature, humidity, pH, EC, and CO2.

*Additional sensors and parameters can be added upon request
**The sensor type and sensor combination are based on your farm type
Autodoser
Designed to deliver precise and consistent nutrient dosing automatically. Using real-time sensor readings(pH and EC), the Autodoser accurately adjusts dosing volumes to maintain optimal solution balance, eliminating guesswork and manual intervention. This ensures stable growing conditions, reduces nutrient waste, and keeps crops within ideal parameters at all times.

Cloud Platform
Built on IoT architecture, Nexus Pro provides real-time telemetry and control via a secure cloud platform, giving users the power to manage their farms anytime, anywhere.

Historical Data
Nexus Pro offers access to 6 months of historical data, enabling users to track and analyse trends over time for key environmental and operational parameters. This data can be viewed in interactive graphs for quick visual insights or exported in CSV format for deeper analysis, reporting, or integration with other systems. Whether you're fine-tuning your grow cycles or reviewing past performance, Nexus ensures you have the data you need at your fingertips.

Multi-Channel Alert
Smart anomaly detection that continuously monitors all connected sensors and devices to ensure optimal operation. When irregularities occur, such as device going offline or any parameter irregularities, Nexus Pro triggers one or more of three alert types based on the severity of the issue. Alerts are categorised into caution, warning or critical levels, helping users prioritise their response. Notifications are sent via the mobile app or email. Built for precision farming, this multi-channel, severity-based alert system ensures you're always informed and ready to respond before production is impacted.

Connectivity
Flexible connectivity options to suit various farm environments. Choose between WiFi-only or WiFi + Cellular (NB-IoT) for enhanced reliability. The NB-IoT (Narrowband Internet of Things) option is especially ideal for remote or rural locations where stable WiFi access may be limited, ensuring continuous data transmission and system control regardless of infrastructure limitations.

NB-IoT operates over existing cellular networks but uses a dedicated, narrow band of frequency that allows for strong signal penetration through buildings and greenhouses
*NB-IoT cellular subscription available at RM300 per year.
Over-The-Air (OTA) update
The system receives automatic software updates without any manual intervention. This ensures that your device is always running the latest version, with new features, performance enhancements, and bug fixes from continuous improvements.
