Name: AM308L 8-in-1 IAQ Sensor | Milesight
Brand: Milesight
SKU: AM308L

AM308L Description

Overview

The AM308L is the screen-free all-in-one model of the Milesight AM300 series. It monitors eight indoor air quality parameters at once, giving a complete view of comfort, ventilation and particulate levels from one compact device.

Sensing

Eight sensors cover temperature, humidity, light, PIR motion, CO2, TVOC, barometric pressure and PM2.5 & PM10. Laser scattering measures fine and coarse dust, while NDIR keeps CO2 readings accurate.

Discreet Design

Unlike the AM308 with its E-ink display, the AM308L is screen-free for interiors where a visible screen is unwanted. A traffic-light indicator and buzzer still flag status and threshold alarms.

Air Quality Insight

Combining gases, particulates and comfort metrics, the AM308L helps teams spot poor ventilation and pollution early and act before conditions affect people.

Power

The AM308L runs on four ER14505 batteries or Type-C power. A smart power-saving mode pauses updates while a room stays vacant to extend service life.

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

AM308L Industrial Applications

Workplace

Offices get a full air-quality picture, from CO2 to particulates, to protect wellbeing and productivity. The screen-free body keeps interiors clean.

Education

Classrooms monitor CO2, dust and comfort to support healthy learning. Local alarms flag issues even before the network reports them.

Healthcare

Clinics and care homes track particulates and ventilation for safer spaces. Reliable storage and retransmission protect data continuity.

Public Buildings

Malls, airports and public venues watch air quality across many zones. LoRaWAN enables wide, low-power coverage with minimal wiring.
