Milesight AM103L-868M – Indoor Air Quality Sensor (CO₂, Temperature & Humidity, LoRaWAN®)

The Milesight AM103L-868M is a versatile indoor environmental sensor engineered to monitor key air quality parameters — carbon dioxide (CO₂), temperature, and humidity — simultaneously. Using a nondispersive infrared (NDIR) sensor for CO₂ and Sensirion’s digital CMOSens® MEMS technology for temperature and humidity, it delivers highly accurate and stable readings.

Data is transmitted wirelessly over LoRaWAN® (Class A, OTAA/ABP), ensuring energy-efficient long-range communication with Milesight gateways or other compatible LoRaWAN® network servers. The AM103L, the display-free version of the AM103 series, offers extended battery life of up to 5 years for maintenance-free operation.

The device includes a traffic light-style LED indicator that visually represents CO₂ concentration levels, allowing for an instant understanding of indoor air quality. With onboard data storage (640 entries) and data retransmission, it guarantees that no readings are lost even during network outages.

Configuration and calibration can be performed quickly through the Milesight NFC mobile app, and integration with Milesight IoT Cloud enables centralized monitoring, analytics, and alert management. Its compact white PC + ABS housing provides a clean aesthetic and durability, with IP30 protection and flexible wall-mount installation using 3M adhesive or screws.
