HU-301 LoRaWAN Wireless Smoke Alarm
Smart Smoke Detection with Remote Monitoring and Real-Time Alerts
The HU-301 LoRaWAN Wireless Smoke Alarm is an IoT-enabled fire detection device designed for smart buildings and remote safety monitoring applications. Combining high-sensitivity photoelectric smoke detection with temperature and humidity sensing, the HU-301 provides local audible and visual alarms while transmitting alarm events and device status to a cloud platform via a LoRaWAN network.
With long-range wireless communication, low-power operation, and remote device monitoring capabilities, the HU-301 helps system integrators and facility managers improve fire safety monitoring across residential buildings, offices, hotels, warehouses, and other indoor environments.
Key Features
- High-Sensitivity Smoke Detection — Photoelectric sensing technology detects smoke and triggers local audible and visual alarms.
- LoRaWAN Connectivity — Transmits alarm events, device status, and environmental data to a compatible LoRaWAN gateway and cloud platform.
- Remote Monitoring and Management — Supports centralized device monitoring, alarm reporting, and integration with compatible IoT platforms.
- Temperature and Humidity Monitoring — Provides environmental data to support remote monitoring and system management.
- Low-Power Design — Separate power supplies for smoke detection and wireless communication support an extended operating life under specified conditions.
- Audible and Visual Alerts — A built-in buzzer and visual indicator provide local warnings when smoke is detected.
- Flexible Deployment — Suitable for integration into smart building and IoT-based safety monitoring systems.
System Architecture
The HU-301 can be deployed as part of an IoT smoke detection system:
HU-301 Smoke Alarm → LoRaWAN Gateway → Cloud Platform → Mobile App / Monitoring and Control Center
The gateway collects data from connected devices and forwards it to the cloud platform through a supported backhaul connection, such as Ethernet or 4G. The platform can support centralized device management, alarm notifications, status monitoring, and historical data analysis. Mobile access and remote management depend on the capabilities of the connected platform and application.
