OverviewThe AM300 Series are all‑in‑one LoRaWAN indoor air quality (IAQ) sensors offering modular configurations (from 4 to 9 measured parameters depending on model) to monitor temperature, humidity, light, motion/occupancy and a variety of gas/particulate sensors. Devices support local storage, retransmission after outages and multiple power options for flexible deployment.
Key features- All‑in‑one IAQ platform: configurable sensor combinations (PM2.5/PM10, CO2, TVOC, HCHO or O3, etc.).
- LoRaWAN wireless connectivity (OTAA/ABP) for long‑range, low‑power transmission.
- Optional 4.2" B/W E‑Ink display on selected models for local visualization and multiple layouts.
- On‑device IAQ indicators: emoticons and traffic‑light LEDs for instant status recognition.
- Onboard buzzer/alarm option on selected models for audible alerts.
- NFC and USB Type‑C supported for fast configuration; mobile app and PC tools available for bulk setup.
- Local buffering and retransmission to prevent data loss during network disruption.
- Battery or USB Type‑C power depending on model for flexible installation.
Sensors & Model highlights- Series examples: AM304L, AM305L, AM307, AM308 / AM308L, AM319.
- Typical sensors: temperature (MEMS), humidity (MEMS), illuminance (photodiode), PIR motion/occupancy.
- Optional sensing: TVOC (MOX), CO2 (NDIR), PM2.5 & PM10 (laser scattering), barometric pressure, HCHO or O3 (electrochemical) depending on model.
IAQ at a glance- Emoticon + traffic‑light display for immediate air quality feedback.
- Optional larger E‑Ink for richer local UI on AM307/AM308/AM319.
- Audible alarm option on selected models for on‑site alerts.
Operation & power- Battery‑powered configurations with smart power saving (PIR‑based vacancy optimization) for multi‑year operation (model‑dependent).
- USB Type‑C power available on some models (AM319 supports Type‑C explicitly).
- Example battery life (10 min interval, ~25 °C): AM304L ~7 years; AM305L ~6 years; AM307 ~3 years; AM308 ~1 year; AM308L ~1.5 years (actual life varies with settings and region).
Connectivity & integration- LoRaWAN support across regional frequency variants; OTAA/ABP supported.
- Onboard data buffering and retransmission to ensure delivery after temporary outages.
- Integration with Milesight device management and cloud platforms; open APIs/webhooks and payload decoders for third‑party integration.
Applications- Smart buildings and offices: environmental monitoring, occupancy detection and HVAC optimization.
- Education facilities and classrooms: air quality monitoring and ventilation control support.
- Transportation hubs and retail: comfort and compliance monitoring.
- Laboratory, healthcare and other indoor spaces requiring environmental data and alerts.
Certifications & compliance- CE / RED / FCC (region/model dependent).
- RoHS compliance.
