# MacSync-WT1 Wi-Fi Temperature & Humidity Sensor Datasheet

## Product Overview

**MacSync-WT1** is a compact, **Wi-Fi–based temperature and humidity sensor with an inbuilt battery**, designed for accurate indoor and semi‑industrial environmental monitoring where direct IP connectivity is preferred. It enables real-time climate data transmission over standard Wi‑Fi networks without the need for gateways or long‑range network infrastructure.

Engineered with industrial‑grade sensing elements and optimized power management, MacSync‑WT1 delivers fast response, low drift, and long‑term measurement stability while operating on battery power using intelligent sleep‑wake cycles. This makes it ideal for deployments where wired power is unavailable but reliable Wi‑Fi coverage exists.

The device securely publishes temperature and humidity data to **local servers, on‑premise dashboards, or cloud platforms** using standard protocols such as **MQTT, HTTP, and HTTPS**. Built‑in BLE support allows easy provisioning, diagnostics, and configuration through the Macnman Maya mobile application.

Housed in a rugged, ingress‑protected enclosure, MacSync‑WT1 is well suited for **smart buildings, HVAC systems, cold rooms, warehouses, laboratories, healthcare facilities, and industrial indoor environments**, delivering low‑latency, reliable Wi‑Fi‑based environmental monitoring with minimal maintenance.
