Indoor air quality sensor AM102

relative humiditytemperatureLoRaWAN

Overview
The AM102 / AM102L is a compact LoRaWAN® indoor IAQ sensor for temperature and humidity monitoring, designed for multi-year battery operation and flexible deployments. An optional variant (AM103 series) adds CO2 monitoring. The AM102 features a 2.13-inch B/W E-Ink display for on-site readings; the AM102L is a screen-free version for discreet installations.

Dual Models

• AM102: 2.13-inch black & white E-Ink display for instant temperature and humidity readings; light/dark modes; typical battery life up to 7 years under standard test conditions.
• AM102L: Screen-free design for aesthetic or hidden mounting; typical battery life up to 9 years under standard test conditions.

Key Features

• LoRaWAN® wireless transmission (OTAA/ABP, Class A) for long-range, low-power connectivity.
• Local visible status indicator (traffic-light style) for quick IAQ assessment.
• High-precision temperature and humidity sensing (digital CMOSens® MEMS sensor).
• One-tap NFC configuration via mobile app (Milesight ToolBox) for fast commissioning.
• Flexible mounting: wall mount with anti-theft Torx screws or quick adhesive using 3M tape.
• Power-saving modes: Smart Screen Mode and Hibernation Mode to maximize battery life.
• Local data storage and retransmission for temporary network outages; tamper/child-lock protections for managed environments.

Applications

• Indoor air quality monitoring in offices, schools, museums, hospitals and retail spaces.
• Integration with HVAC and building automation for occupant comfort and energy efficiency.
• Cold chain and pharmaceutical storage monitoring as part of integrated solutions (where temperature/humidity tracking is required).
