Product Overview
The HL200 Power & Environment Monitor is an intelligent monitoring host system co-developed by HMK TECH and German HELM, built on a proven pressure monitoring platform and engineered to European standards. Designed for mission-critical infrastructure, it delivers comprehensive environmental surveillance for telecom cabinets, data centers, and industrial equipment rooms with 5–10 years of maintenance-free reliability.
At its core, the HL200 runs UCOS real-time operating system on an industrial-grade STM32F103 processor (72 MHz), ensuring deterministic response times for critical alarm events. The system consolidates all sensor inputs — temperature, humidity, smoke, water leak, vibration, tilt, and door access — through standardized RJ45 interfaces with built-in POE, eliminating complex wiring and reducing installation time by up to 60% compared to traditional monitoring systems.
The modular architecture supports expansion via plug-in UPS and air conditioning communication modules, multiple RS485/RS232 interfaces, and an external touchscreen with professional graphical UI. Remote monitoring is available through Ethernet or optional Wi-Fi, providing real-time dashboards and alarm notifications. All hardware circuits and firmware modules have been certified by European authorities, ensuring safety and regulatory compliance for deployment across global markets.

Key Features
RJ45 Unified Interface
All analog and digital sensor signals are converted to standardized RJ45 network ports, ensuring safe, clean wiring with easy upgrade paths. This unified approach eliminates mixed cabling and reduces installation errors significantly.
Built-in POE Power
Communication and 12V power are delivered through a single RJ45 cable, allowing sensors and modules to connect via standard Ethernet cables. This simplifies cascade expansion and eliminates separate power wiring.
UCOS Real-Time OS
Industrial-grade STM32F103 processor running UCOS provides deterministic response times for alarm events. The 72 MHz clock speed and optimized firmware ensure reliable operation even under peak monitoring loads.
Modular Expansion
Plug-in modules for UPS monitoring, air conditioning control, and additional sensor arrays. Multiple RS485 and RS232 interfaces support diverse third-party devices without firmware changes.
Touchscreen Display
External touchscreen interface with professional graphical UI designed for intuitive operation. View real-time sensor data, alarm status, and system configuration without needing a laptop or remote connection.
European Certification
All hardware circuits and firmware modules certified by European authorities. Ensures regulatory compliance for global deployment in telecom, government, and enterprise environments.
Applications
Telecom Outdoor Cabinets
Monitor temperature, humidity, smoke, and intrusion in remote telecom base station cabinets. Built-in POE and Ethernet enable centralized monitoring across hundreds of distributed sites without on-site personnel.
Data Center Rooms
Comprehensive environmental monitoring for server rooms including temperature mapping, water leak detection, and fire alarm integration. The 1U rack form factor integrates seamlessly into existing infrastructure.
Integrated Cabinets
All-in-one monitoring for edge computing and integrated telecom cabinets. Vibration and tilt sensors detect unauthorized access or structural concerns, while cloud locks provide remote door management.
Power Distribution Rooms
Monitor electrical infrastructure environments including UPS status, ambient conditions, and access control. Relay outputs enable automatic ventilation or emergency power switching based on sensor thresholds.
Government & Finance IT
Secure monitoring for government data centers and financial institution server rooms. European-certified hardware meets stringent security and compliance requirements for sensitive installations.
Industrial Equipment Rooms
Protect critical industrial control systems with continuous environmental monitoring. Expandable sensor channels and RS485 interfaces integrate with existing PLC and SCADA systems for unified facility management.
Ordering Guide
The HL200 uses a modular ordering code system. Each code segment specifies a sensor or module type and quantity. Contact our engineering team for a customized configuration.
| Code | Description | Example |
|---|---|---|
| HL200 | Base model — monitoring host with 1U chassis | HL200 |
| D[n] | Smart cloud lock quantity | D2 = 2 cloud locks |
| T[x][n] | Temperature & humidity sensor type and quantity | T12 = Type T1, 2 units |
| S[x][n] | Smoke detector type and quantity | S12 = Type S1, 2 units |
| AL[x][n] | Alarm / door magnetic sensor type and quantity | AL12 = Type AL1, 2 units |
| PU[x][n] | UPS communication module type and quantity | PU22 = Type PU2, 2 units |
| PA[x][n] | Air conditioning communication module type and quantity | PA22 = Type PA2, 2 units |
Example order: HL200-D2-T12-S12-AL12-PU22-PA22 = HL200 host + 8″ touchscreen + 2x temp/humidity sensors + 2x smoke detectors + 2x electromagnetic locks + 1x UPS module + 1x AC module.
