With the large-scale application of hydrogen energy in fields such as energy storage, industrial production, and new energy, the safety risks posed by hydrogen leakage have become increasingly prominent. The LoRaWAN hydrogen sensor launched by ZONEWU, based on the three-electrode electrochemical detection principle, integrates high-precision collection, wireless transmission, and intelligent early warning functions. With advantages such as high sensitivity and strong stability, it has become a core device for hydrogen safety monitoring in various industries, accurately meeting the safety protection needs of multiple scenarios.

Energy Storage Safety: Fortifying the Defenses of Hydrogen Energy and Battery Energy Storage

Scenarios such as lithium battery energy storage stations and hydrogen fuel cell storage systems are prone to hydrogen leakage due to equipment failures, overcharging, and overheating. Once the concentration exceeds the standard, it may trigger explosion risks. This sensor has a hydrogen measurement range of 0-1000ppm and a high resolution of 1ppm, which can accurately detect trace leaks and achieve early warning. It supports custom upper and lower thresholds for hydrogen (1-65535ppm). When the concentration exceeds the standard, it can link with DO transistor output to trigger local alarm or power-off control, blocking dangers from the source. Equipped with LoRaWAN remote transmission technology, it covers large energy storage sites, allowing managers to centrally monitor multi-point data through the platform without on-site duty, greatly improving management efficiency. Its 5-28VDC wide voltage power supply design is suitable for the complex power supply environment of energy storage scenarios, ensuring 24-hour stable operation.

Industrial production scenario: Safety barriers adapted to harsh working conditions

In scenarios such as chemical enterprises, hydrogen production lines, and metallurgical factories, hydrogen, as a raw material or by-product, faces leakage risks throughout the entire process of production, storage, and transportation. The sensor adopts a high-performance microprocessor and anti-interference design, enabling it to work stably in harsh industrial environments with temperatures ranging from -20℃ to 50℃ and humidity ranging from 15% to 90% RH (without condensation), and is not affected by electromagnetic interference or other gases. The default reporting cycle is 5 minutes (which can be flexibly adjusted from 1 to 65535 seconds). In case of abnormalities, it will automatically report continuously for 3 times to ensure that staff can respond quickly. It supports multiple global frequency bands such as CN470, EU868, and US915, perfectly adapting to the deployment needs of transnational industrial projects. There is no need to adjust or replace equipment due to regional differences, thus reducing procurement and maintenance costs.

Confined Space Monitoring: Solving the Difficulties in Complex Environment Monitoring

Underground hydrogen pipelines, tunnels, sealed warehouses, and other confined spaces have poor ventilation, making hydrogen prone to accumulation. Additionally, the installation and maintenance of traditional wired sensors are inconvenient. This sensor, with dimensions of only 110mm × 85mm × 44mm and a weight of 120g, is compact and lightweight, allowing flexible installation in narrow spaces. It adopts a wireless transmission design, eliminating the need for complex wiring, and its low-power consumption feature supports long-term operation, significantly reducing the workload of construction and later maintenance. It has a built-in green LED indicator: blinking indicates that it is accessing the network, and being steadily on means the connection is successful, facilitating on-site personnel to quickly troubleshoot network faults. It supports OTAA network access and Class A/C working modes (Class C by default), ensuring stable signal transmission and enabling accurate data reporting even in confined environments with weak signals.

Normalizing Environmental Monitoring: Adaptation to Multi-domain Security Control

Scenarios that require regular monitoring of hydrogen concentration, such as scientific research institutions and hydrogen refueling stations, have extremely high requirements for the accuracy and stability of sensors. This sensor adopts the electrochemical detection principle, featuring high measurement accuracy and small drift. It can perform zero-point calibration through the FE14EF command every 6-12 months to maintain long-term data reliability. The TYPE-C interface integrates both configuration and power supply functions. Combined with a dedicated configuration tool for the Windows system, it can flexibly adjust parameters such as data collection cycles and reporting cycles to meet the personalized monitoring needs of different scenarios. The device comes with preset parameters such as DevEUI and AppEUI from the factory, supports custom modifications, and can be quickly connected to existing LoRaWAN networks, ensuring high deployment efficiency.
