Milesight AM300 – LoRaWAN Indoor Air Quality Sensor (IAQ)

Complete indoor air quality and climate monitoring

The AM300 series is designed to monitor indoor air quality (IAQ) and comfort parameters across a wide range of environments. By combining multiple sensors in one device, it provides direct insight into air quality, occupancy, and environmental conditions.

Using LoRaWAN® technology, the AM300 enables reliable, long-range, and energy-efficient wireless communication. This makes it highly suitable for scalable deployments in buildings without complex wiring.

Up to 9 parameters in one device

Depending on the model, the AM300 can measure:

• Temperature

• Relative humidity

• CO₂

• TVOC (total volatile organic compounds)

• Particulate matter (PM2.5 / PM10)

• Light intensity

• Barometric pressure

• Motion (PIR)

• Formaldehyde (HCHO) or ozone (O₃)

One device, complete insight into air quality and comfort.

Instant insight with E-ink display and IAQ indicator

The AM300 features an optional 4.2” E-ink display showing real-time data:

• Clear visual display of measurements

• Emoticon-based air quality indication

• Traffic light status (good / moderate / poor)

Air quality at a glance, even without software.
