Beschreibung
The Milesight AM319 is a 9-in-1 LoRaWAN indoor air quality sensor for offices, schools, healthcare, retail and public buildings. It measures CO2, PM2.5, PM10, TVOC, formaldehyde (HCHO) or ozone (O3), temperature, humidity, barometric pressure, light and motion, shows the values on a 4.2-inch E-ink display and sends them over LoRaWAN for healthy-building and ESG reporting.

Key features
- 9 measurements in one device, including PM2.5 and PM10 (laser scattering) and a photoacoustic CO2 sensor.
- HCHO or O3: electrochemical formaldehyde or ozone sensor, replaceable (HCHO working life 6 years, O3 2 years).
- Visible on the wall: 4.2-inch E-ink screen, traffic-light LED and buzzer for threshold alarms.
- Always on: powered by 5 V via USB Type-C; LoRaWAN Class C.
- Data safety: stores up to 18,000 entries on the device.
Which version do I need?
SKUs match the Milesight model (AM319) plus the LoRaWAN hardware band. Milesight builds the AM319 with either an HCHO sensor (part numbers HCHO-IR and HCHO-IR-W) or an O3 sensor; tell us which gas you need when ordering.

Sensor and software: what you get
On the sensor: live readings, threshold alarms and LoRaWAN data. In software: indoor air quality dashboards, alerts, ventilation control based on occupancy and ESG reports. Use the AM319 with VemSpace, which comes with a 60-day free trial (see software plans). The hardware price does not include a software licence.
Installation and accessories
Mount the AM319 on an inside wall near a USB power outlet, at breathing height and away from windows, doors and vents. It needs a LoRaWAN gateway on the same frequency plan, such as the UG65 or UG67. For a battery-powered sensor without particles see the AM307; for room occupancy add the VS121.
Frequently asked questions
Does the Milesight AM319 measure PM2.5?
Yes, PM2.5 and PM10 with a laser scattering sensor, 0–1000 µg/m³.
Can the AM319 run on batteries?
No. It is powered by 5 V via USB Type-C. For battery operation choose the AM307.
HCHO or O3 version?
Choose HCHO for formaldehyde from furniture and building materials, O3 where ozone is a concern. The gas sensors are replaceable.
Which LoRaWAN frequency do I need?
868M for Europe, the Middle East, Africa, India and Russia; 915M for the Americas, Australia, Korea and most of Asia-Pacific.
