MacSync-LH2S-X1 Datasheet
Product Overview
MacSync-LH2S-X1 is an industrial-grade LoRaWAN® Hydrogen Sulfide (H₂S) gas sensor designed for continuous, quantitative monitoring of H₂S concentration in ppm across industrial, municipal, and environmental applications.
Built around a high-accuracy electrochemical H₂S sensing element, the device delivers reliable, stable, and repeatable gas concentration measurements, enabling early detection of toxic gas buildup and proactive safety intervention. Hydrogen sulfide is a highly hazardous and corrosive gas commonly present in sewage systems, wastewater treatment plants, industrial processes, landfills, and confined spaces, making accurate monitoring critical for worker safety and regulatory compliance.
MacSync-LH2S-X1 operates on an ultra‑low‑power LoRaWAN® Class A architecture, providing long-range wireless connectivity and multi‑year battery life even in remote or unmanned locations. Its rugged, ingress‑protected enclosure ensures dependable operation in harsh outdoor and industrial environments.
The sensor supports threshold-based alerts, trend analysis, and periodic reporting, allowing seamless integration with SCADA systems, safety dashboards, and cloud platforms over public or private LoRaWAN® networks. Optional BLE‑based configuration via the Macnman Maya App simplifies installation, diagnostics, and maintenance.
From STP / WWTP safety monitoring and sewer gas detection to industrial process safety and confined-space monitoring, MacSync-LH2S-X1 transforms toxic H₂S gas data into actionable, data‑driven insights.
