Description

The Milesight AM103 & AM103L are cost-effective 3-in-1 LoRaWAN indoor air-quality sensors measuring CO2, temperature, and humidity — the core parameters for healthy, well-ventilated indoor spaces. Using NDIR CO2 sensing and Digital CMOSens® MEMS, they suit smart offices, schools, and healthcare facilities.

The AM103 includes a 2.13-inch E-ink display showing CO2 trends, humidity, and status icons at a glance, while the AM103L is a display-less version for back-end monitoring. Both are compact, run for years on replaceable batteries, and set up tool-free via NFC.

Core Capabilities

3-in-1 CO2, Temp & Humidity NDIR CO2 (400–5000 ppm, ±(30 ppm + 3% of reading)), temperature (±0.2°C, 0–60°C) and humidity (±2% RH at 25°C) via Digital CMOSens® MEMS — accurate IAQ essentials in one compact device.
Optional At-a-Glance E-ink Display The AM103's 2.13-inch E-ink screen highlights CO2 trends, humidity, status icons, and last-update time in clear fonts for on-site monitoring. The AM103L omits the screen for back-end-only deployments.
Up to 4-Year Battery Life Two replaceable 2700 mAh ER14505 Li-SOCl₂ batteries deliver up to 4 years of operation, with screen-hibernate and smart-screen energy-saving modes (and the AM103L lasting longer without a display).
NFC Setup & CO2 Calibration Configure tool-free via NFC with the Milesight ToolBox app. Supports manual and automatic background CO2 calibration, threshold alarms, on-device data storage, and data retransmission.

Typical Applications

Offices & Smart Workplaces: Monitor CO2 and comfort to drive demand-based ventilation, improve productivity, and display air-quality status at a glance on the AM103 screen.
Schools & Classrooms: Track CO2 build-up to maintain healthy, alert learning environments and inform ventilation scheduling.
Healthcare & Public Buildings: Maintain compliant indoor air quality in clinics, waiting rooms, and public spaces with reliable CO2 and comfort data.
Building Management & HVAC: Feed CO2, temperature, and humidity data into HVAC and building automation systems (via a LoRaWAN gateway) for energy-efficient ventilation.

Technical Integration

Key points for adding the AM103 / AM103L to your LoRaWAN network:

Connectivity: LoRaWAN® Class A (OTAA/ABP); EU868 (also CN470, US915, AU915, AS923, KR920, IN865, RU864).
Network server & platform: Integrates with Milesight IoT Cloud and the Development Platform; works with standard servers like The Things Stack and ChirpStack, feeding HVAC and building automation systems via a gateway.
Power: Two 2700 mAh ER14505 Li-SOCl₂ batteries (up to ~4 years), with screen-hibernate and smart-screen energy-saving modes.
Configuration: Tool-free via NFC with the Milesight ToolBox app and downlink commands; CO2 supports manual and automatic background calibration.
Mounting & environment: Compact IP30 enclosure (68 × 65 × 20.5 mm) with 3M tape or anti-theft screws; operates −20 °C to +60 °C (E-ink screen 0–40 °C).
Setup help: For deployment or gateway selection support, contact the shopioT technical team.

Frequently Asked Questions

What does the AM103 measure?

CO2 (NDIR, 400–5000 ppm), temperature, and humidity — the three core IAQ parameters. For added TVOC/PM, see the AM307/AM308; for temperature + humidity only, the AM102.

What's the difference between AM103 and AM103L?

Same 3-in-1 sensors and accuracy. The AM103 adds a 2.13-inch E-ink display; the AM103L has no display and a longer battery life.

How accurate is the CO2 sensor?

NDIR CO2 with ±(30 ppm + 3% of reading) accuracy across 400–5000 ppm, plus manual and automatic background calibration (ABC).

How is it powered?

By two replaceable 2700 mAh ER14505 Li-SOCl₂ batteries, with screen-hibernate and smart-screen energy-saving modes for up to ~4 years of life.

Does it need a LoRaWAN gateway?

Yes. It reports over LoRaWAN® (Class A) to a gateway and network server (e.g. The Things Stack, ChirpStack, or Milesight UG56/UG65). A gateway is sold separately.

How is it configured and mounted?

Tool-free via NFC with the Milesight ToolBox app; it mounts with 3M tape or anti-theft wall screws.
