# MacSync-WCO2X Datasheet

## Product Overview

**MacSync‑WCO2X** is a high‑accuracy **Wi‑Fi–based CO₂ indoor air quality (IAQ) sensor** designed for continuous monitoring of carbon dioxide levels in smart buildings, workplaces, schools, hospitals, and industrial indoor environments where reliable IP connectivity is available.

Powered by an industrial‑grade **NDIR CO₂ sensing module** with automatic baseline calibration, the device delivers precise CO₂ measurements in ppm along with **temperature and humidity monitoring**, providing complete indoor air quality intelligence for ventilation assessment and HVAC optimization.

MacSync‑WCO2X communicates directly over **standard Wi‑Fi networks (2.4 GHz / 5 GHz)** to **on‑premise servers, building management systems (BMS), SCADA platforms, or cloud dashboards** using industry‑standard protocols such as **MQTT, HTTP, and HTTPS**—without requiring gateways or long‑range wireless infrastructure.

Designed for both new installations and retrofit deployments, the sensor supports **battery‑operated and externally powered variants**, enabling flexible installation across diverse indoor locations. **BLE‑based provisioning via the Macnman Maya App** allows fast configuration, diagnostics, and parameter updates without specialized tools.

From **classroom ventilation compliance and office occupancy insights** to **healthcare safety monitoring and industrial workspace air‑quality management**, **MacSync‑WCO2X transforms indoor CO₂ data into actionable intelligence**, enabling healthier, more energy‑efficient, and compliant indoor environments.
