    Description

    AM304L Description

    Overview

    The AM304L is the entry model of the Milesight AM300 series, a screen-free 4-in-1 sensor that tracks indoor temperature, humidity, light and occupancy. It gives facility teams a clear view of comfort and space usage to support healthier, more efficient buildings.

    Sensing

    Four sensors cover the essentials: temperature, relative humidity, ambient light and PIR motion. Together they show whether a room is comfortable and in use, all from a single compact device.

    Discreet Design

    With no display, the AM304L 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 AM304L talk directly to other Milesight devices without a gateway, enabling ultra-low-latency local automation such as lighting or HVAC triggers.

    Power

    Without a screen to drive, the AM304L reaches up to 14 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

    AM304L Industrial Applications

    Workplace

    Offices monitor comfort and desk occupancy to optimise space and energy use. The screen-free body keeps interiors clean and unobtrusive.

    Education

    Classrooms track temperature, humidity and presence for healthier learning. D2D control can drive lighting or ventilation automatically.

    Healthcare

    Clinics and care homes keep rooms within comfortable, safe ranges. Long battery life reduces maintenance across many spaces.

    Public Buildings

    Libraries and public spaces maintain healthy indoor conditions. LoRaWAN enables wide, low-power coverage with minimal wiring.
