Overview
The AM102L is the screen-free version of the Milesight 2-in-1 IAQ sensor. It delivers precise indoor temperature and humidity readings to help create healthier spaces and save energy across commercial and public buildings.
With no display, the AM102L blends quietly into any interior where a visible screen is unwanted. This suits museums, galleries, and design-led offices that need monitoring without clutter.
High-precision sensing gives temperature accuracy of ± 0.2 °C from 0 to 60 °C and humidity accuracy of ± 2% RH at 25 °C. A three-colour indicator shows environment status at a glance.
Without a screen to drive, the AM102L reaches up to 9 years of battery life from two ER14505 cells. Hibernation mode extends life further during long unoccupied periods.
One-tap NFC configuration through the Milesight ToolBox app makes setup quick. Wall mounting with anti-theft Torx screws or 3M tape keeps installation flexible.
The sensor integrates with HVAC, thermostats, LoRaWAN gateways, and building automation systems. Real-time data supports automated control for safer, more efficient indoor environments.
