Introducing our LoRaWAN Gas Hydrogen Sulfide & Sulfur Dioxide (SO₂) Sensor — a state-of-the-art IoT wireless sensing solution engineered on the robust foundation of LoRa technology.
Integrated with dual-core sensing modules for hydrogen sulfide and sulfur dioxide detection, plus an auxiliary temperature and humidity sensor, this device leverages advanced electrochemical principles to deliver real-time, high-precision monitoring of multi-gas concentrations and ambient climate parameters.
What truly sets it apart are its three core strengths:
Precise measurement: Calibrated with professional-grade algorithms to ensure minimal margin of error, capturing even subtle fluctuations in gas levels for reliable data insights.
Stable performance: Built with industrial-grade components, it maintains consistent operation in harsh environments such as chemical plants and industrial emission sites, free from signal drift or data interruption.
Low energy consumption: Optimized power management design supports long-lasting wireless transmission without frequent battery replacement, drastically reducing maintenance costs.
Thanks to these superior features, our LoRaWAN H₂S & SO₂ Sensor is perfectly suited for long-term, continuous deployment across a wide range of scenarios, including environmental quality monitoring, industrial pollution control, chemical plant safety supervision, and urban air quality management.
