AM319 Description

Core Purpose

The AM319 is designed to monitor indoor environmental conditions in real time. It brings together multiple sensors in a single device to help users understand air quality, comfort, and occupancy inside buildings. The on-device screen provides immediate visibility without needing external tools.

Monitoring Capabilities

The device measures key indoor factors such as temperature, humidity, air quality, particulate matter, and carbon dioxide levels. This allows building operators to track comfort and health-related conditions throughout the day. Motion detection adds basic occupancy awareness for indoor spaces.

Visual Feedback and Alerts

A built-in E-ink display shows live readings and comfort indicators that are easy to understand at a glance. Traffic light indicators and a buzzer provide clear alerts when thresholds are exceeded. This helps users react quickly to changes without checking software dashboards.

Connectivity and Data Handling

Sensor data is transmitted using LoRaWAN for long-range, low-power communication. The device stores historical data locally and can retransmit it if a connection is interrupted, reducing the risk of data loss. Remote access is supported through Milesight management platforms.

Power and Installation

The AM319 is powered through a standard USB Type-C connection, making installation simple in indoor environments. It is designed for wall mounting using tape or screws and operates reliably across common indoor temperature and humidity ranges.

Industry Applications

AM319 Industrial Applications

Commercial Offices

The AM319 helps offices monitor air quality, temperature, and comfort levels to support employee well-being. Visual alerts make it easy to spot issues like poor ventilation or elevated CO₂ levels.

Education Facilities

In classrooms and campuses, the device supports healthier learning environments by tracking air quality and occupancy-related conditions. Real-time display helps staff respond quickly during school hours.

Healthcare Buildings

Hospitals and clinics can use the AM319 to observe indoor environmental conditions that affect patient comfort. Continuous monitoring supports stable and controlled indoor spaces.

Retail and Public Spaces

Retail stores and public buildings benefit from clear visibility into indoor air conditions. Motion detection and air quality data help maintain comfortable environments for visitors.

Smart Building Management

The device fits into smart building systems by sending sensor data to central platforms. This supports long-term analysis and informed decisions about indoor environmental control.
