Overview
AM319 overview
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.
Key features
E-ink display
A 4.2-inch black and white screen shows comfort levels on the wall.
Threshold alarms
Sound and light alarms when a reading crosses its threshold.
Local storage
Keeps up to 18,000 records on the device for later recovery.
LoRaWAN Class C
EU868 and other bands, OTAA or ABP, with internal antennas.
USB-C power
5 V at 1 A through a USB Type-C connector.
