    Description

    AM305L Description

    Overview

    The AM305L is a screen-free 5-in-1 sensor in the Milesight AM300 series. It adds carbon dioxide monitoring to temperature, humidity, light and occupancy sensing, giving a fuller picture of indoor air quality and comfort.

    Sensing

    Five sensors cover temperature, relative humidity, ambient light, PIR motion and CO2. NDIR measurement keeps CO2 readings accurate and stable, a key marker of ventilation and crowding.

    Discreet Design

    With no display, the AM305L blends quietly into any interior where a visible screen is unwanted. A built-in traffic-light indicator still shows status at a glance.

    Direct Control

    Milesight D2D support lets the AM305L talk directly to other Milesight devices without a gateway, enabling ultra-low-latency local automation such as ventilation triggers when CO2 rises.

    Power

    Without a screen to drive, the AM305L reaches up to 11 years of battery life from four ER14505 cells, or runs on Type-C power. A smart power-saving mode pauses updates while a room stays vacant.

    Setup

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

    Industry Applications

    AM305L Industrial Applications

    Workplace

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

    Education

    Classrooms watch CO2 and presence to protect focus and health. D2D control can boost ventilation automatically when levels climb.

    Healthcare

    Clinics and care homes keep rooms ventilated and comfortable. Long battery life reduces maintenance across many spaces.

    Public Buildings

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