MacSync-L-GSX2 Datasheet
Product Overview
MacSync‑L‑GSX2 is a high‑precision LoRaWAN® H₂S & NH₃ gas monitoring sensor, engineered for odor management and hazardous air‑quality surveillance in industrial, municipal, and environmental applications. It continuously detects hydrogen sulfide (H₂S) and ammonia (NH₃) concentrations — gases commonly associated with worker safety risks, toxic exposure, and odor pollution.
Designed for wastewater facilities, refineries, chemical plants, livestock farms, landfills, and smart‑city pollution monitoring, this sensor provides real‑time alerts to prevent dangerous gas accumulation and enable rapid safety response.
With ultra‑long‑range LoRaWAN® wireless connectivity, multi‑year battery operation, and rugged IP65-rated construction, MacSync‑L‑GSX2 ensures reliable deployment in corrosive and harsh outdoor environments. The device also includes BLE support via Maya App, enabling fast provisioning, calibration check, diagnostics, and OTA configuration — without professional tools.
Whether deployed for odor complaint intelligence, worker safety, environmental compliance, or automated ventilation control — MacSync‑L‑GSX2 delivers accurate, secure, and scalable toxic gas monitoring for the most demanding field environments.
