    Description

    AM103L Description

    Overview

    The AM103L is the screen-free version of the Milesight 3-in-1 IAQ sensor. It measures indoor temperature, humidity and carbon dioxide to help create healthier, more comfortable and energy-efficient spaces.

    Sensing

    Three sensors cover temperature, relative humidity and CO2. NDIR measurement keeps CO2 readings accurate and stable, a key marker of ventilation and occupancy.

    Discreet Design

    With no display, the AM103L blends quietly into any interior where a visible screen is unwanted. A built-in traffic-light indicator still shows CO2 status at a glance.

    Power

    Without a screen to drive, the AM103L reaches up to 5 years of battery life from two ER14505 cells. A smart hibernate mode extends life further during long unoccupied periods.

    Setup

    One-tap NFC configuration through the Milesight ToolBox app makes setup quick. Wall mounting with screws or 3M tape keeps installation flexible.

    Ecosystem

    The sensor integrates with HVAC, thermostats, LoRaWAN gateways and building automation systems. Real-time data supports automated ventilation for safer, more efficient indoor environments.

    Industry Applications

    AM103L Industrial Applications

    Workplace

    Offices track CO2 and comfort to keep air fresh and energy use down. The screen-free design keeps interiors clean and unobtrusive.

    Education

    Classrooms watch CO2 levels to protect focus and health. Traffic-light alerts flag when ventilation is needed.

    Healthcare

    Clinics and care homes keep rooms ventilated and comfortable. Reliable data supports safer indoor environments.

    Public Buildings

    Meeting rooms and public spaces maintain healthy CO2 levels across many rooms. LoRaWAN enables wide, low-power coverage with minimal wiring.
