US915 LoRaWAN temperature, humidity and CO2 sensor without display
The Room sensor AM103L MS Temperature, humidity and CO2 without display US Version LoRaWAN is a compact indoor climate sensor for monitoring CO2 concentration, temperature and relative humidity. This version uses the US915 LoRaWAN frequency plan and is intended for compatible networks in the United States.
Measurements are transmitted through LoRaWAN to a compatible US915 LoRaWAN gateway and monitoring platform for remote visualisation, alarms and historical analysis.
CO2 and indoor climate monitoring
The AM103L uses an NDIR sensor to measure CO2 from 400 to 5,000 ppm. It also measures temperature and relative humidity, providing useful data for ventilation control and indoor climate monitoring.
The model has no E-Ink display, but an integrated traffic-light LED provides a clear local indication of the current CO2 status.
Configuration and operation
The sensor is configured through NFC using the Milesight ToolBox app or remotely through LoRaWAN downlink commands. It supports threshold alarms, calibration, storage of up to 640 records and data retransmission after temporary network interruptions.
See the official Milesight AM103L product information and documentation for detailed specifications and configuration guidance.
