# MacSync-WGSX2 Datasheet

## Product Overview

**MacSync‑WGSX2** is a high‑precision **Wi‑Fi–based quantitative H₂S & NH₃ gas monitoring sensor** designed for real‑time measurement of **hydrogen sulfide (H₂S)** and **ammonia (NH₃)** concentrations in ppm for industrial safety, environmental compliance, and occupational health applications within Wi‑Fi‑enabled environments.

Built using **industrial‑grade electrochemical gas sensors**, the device delivers accurate, stable, and repeatable ppm‑level measurements with fast response times, enabling early detection of hazardous gas buildup and proactive safety intervention. Unlike qualitative odor sensors, MacSync‑WGSX2 provides **true quantitative gas concentration data**, making it suitable for regulatory monitoring, safety audits, and process control.

MacSync‑WGSX2 communicates directly over **standard Wi‑Fi networks (2.4 GHz / 5 GHz)** to **on‑premise servers, SCADA systems, safety dashboards, or cloud platforms** using industry‑standard protocols such as **MQTT, HTTP, and HTTPS**, without the need for gateways or long‑range wireless infrastructure.

Housed in a **rugged IP‑rated enclosure**, the sensor is suitable for deployment in **sewage treatment plants (STP), wastewater facilities (WWTP), chemical plants, factories, confined indoor spaces, utility rooms, and industrial work zones** where reliable Wi‑Fi connectivity is available. **BLE‑based configuration via the Macnman Maya App** enables quick provisioning, diagnostics, calibration checks, and maintenance.

Whether deployed for **worker safety, toxic gas exposure monitoring, ventilation control, or compliance reporting**, **MacSync‑WGSX2 delivers reliable, real‑time Wi‑Fi‑based toxic gas monitoring**, transforming hazardous gas risks into actionable data.
