Company Profile
Industrial IoT hardware and cloud solutions from one engineering team
Nengjia focuses on IoT communication terminals, cloud platform customization and industry solutions based on 4G, 5G, Wi-SUN, LoRaWAN, LoRa, Sigfox, ZigBee, NB-IoT, Wi-Fi and gateway technologies.
Our product and solution work covers smart lighting, smart agriculture, smart photovoltaic and smart water management projects, connecting field equipment to practical remote monitoring and control systems.
What We Build
NetJoin IoT is positioned around connected hardware, project delivery and the cloud systems needed to operate distributed outdoor devices.
Cloud platform solutions
Smart lighting, agriculture, photovoltaic and water-management platforms for monitoring, control and project operation.
Custom development
Private deployment, interface matching, firmware behavior and gateway integration support for project-based requirements.
Technical service
A product-and-engineering team focused on stable products, timely support and practical deployment cooperation.
Manufacturing
Production evidence buyers can actually inspect
For industrial gateway projects, stable delivery depends on controlled assembly, repair and inspection workflows. The production photos show real manufacturing, maintenance and PCB-level work instead of generic factory claims.
- Assembly line for IoT gateway and controller products.
- Maintenance and test benches for troubleshooting and verification.
- PCB-level handling for terminal and gateway hardware.
Industry Focus
The company website identifies four major business directions that combine hardware terminals with cloud-platform solutions.
Smart lighting
Smart street-light gateways, single-lamp controllers, centralized controllers and solar street-light IoT controllers.
Smart agriculture
Solar IoT pest-control terminals, insect monitoring systems, weather-station controllers and agriculture sensing projects.
Smart photovoltaic
IoT solar MPPT controllers, solar IoT street-light systems and off-grid solar power-station monitoring.
