Overview
AM308L overview
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.
