Milesight Sensor AM319-868M
Milesight AM319 is an indoor air quality sensor that measures nine parameters including temperature, humidity, CO₂, and particulate matter. It displays results on a 4.2” E-Ink screen with clear indicators and transmits data via LoRaWAN technology for long-range, low-power communication.
General configuration
