LoRa-based portable sensors for rapid on-site safety management
The RN630-KFG is a portable smart sensor designed to ensure worker safety. It simultaneously measures CO, CO₂, O₂, and H₂S, and integrates temperature, humidity, and even Man-Down (no response) and SOS signals.
-
-
Multi-notifications that utilize visual, auditory, and tactile senses
The 1.54″ OLED clearly displays measurement values and alarm status, and the RGB LED (status/alert), high-power buzzer, strong vibration, and white strobe work together to ensure you don’t miss any hazards even in noisy or dark working environments.
-
-
Real-time on-site temperature check
Rather than relying on Korea Meteorological Administration data, the RN630-KFG calculates and displays the perceived temperature based on actual on-site temperature and humidity measured by the system. This can be used to adjust work intensity, set break times, and establish protective equipment standards for work in hot weather and confined or semi-enclosed spaces.
-
-
Supports LoRaWAN low-power long-distance communication
LoRaWAN, the latest international communications protocol, offers the advantage of low power consumption while supporting long-distance communication without additional repeaters. LoRaWAN (Class A) wireless ensures stable data transmission within buildings, plants, and outdoor locations. Even when communication is interrupted, internal buffering and retransmission minimize data loss.
-
-
Field-customized alarm values and profiles
Default alarm values are provided in accordance with industrial safety guidelines, and thresholds, such as upper and lower limits and TWA, can be easily adjusted for each channel to suit your workplace regulations. Alarm history is automatically saved and utilized for follow-up management.
-
-
Rechargeable battery, up to 60 hours of continuous operation
The approximately 8.5 Wh lithium-ion battery ensures reliable operation even during long work hours. It supports rapid charging, and the remaining battery capacity can be intuitively checked on the screen.
-
-
IP65 rating and lightweight design minimize the burden on wearer.
IP65 waterproof and dustproof rating for safe use, lightweight body weighing approximately 175 g, and large clip option reduce fatigue that may occur when worn for long periods of time.
-
-
Management of oxygen deficiency/hydrogen sulfide risks before and during work in confined spaces (manholes and tanks)
Pre-entry checks – Continuous monitoring during operation
Simultaneously measure O₂, H₂S, CO, and CO₂, and immediately alert with a buzzer, vibration, and strobe when thresholds are exceeded. Data is transmitted to the control room via LoRaWAN®, enabling simultaneous processing of phone calls, text messages, and logging.
-
-
Personal safety management for plant/maintenance teams
Portable personal alarm + remote control
Continuous monitoring is possible even when worn by individual workers. Man-Down (no response) and SOS functions immediately notify of an accident, and profile loading standardizes settings during shift changes and site changes.
-
-
Permanent patrols of sewage treatment, oil refinery, and gas facilities
Check for gas leaks and ventilation conditions
Measurements are automatically recorded along regular patrol routes and used for automated report generation. Internal storage and retransmission minimize data loss, even in communication blind spots.
-
-
Safety at warehouse, underground, and tunnel construction sites
High concentration CO₂/CO accumulation advance warning
It continuously monitors ventilation conditions in enclosed and semi-enclosed spaces and simultaneously sends on-site alerts and control notifications when thresholds are reached. It also provides stable, long-distance, low-power transmission, even in unmanned work areas at night.
-
-
Access control to ship cargo holds and grain silos
Gas-free confirmation and history before loading/unloading
CO₂, CO₂, O₂, and H₂S are immediately checked before entry and provide on-site alerts when levels are below or exceed standards. Results are automatically uploaded to Radionode365 via LoRaWAN®, enabling one-stop electronic gas measurement record management.
