Milesight AM103L Indoor Ambience Monitoring Sensor

The Milesight AM103L is a compact indoor ambience monitoring sensor designed to measure temperature, humidity, and CO₂ levels. By combining these measurements with LoRaWAN® connectivity, it provides an effective way to monitor indoor environmental conditions and comfort across offices, classrooms, stores, hospitals, and other indoor spaces.

The AM103L supports local data storage and retransmission to help prevent data loss, while NFC provides quick configuration and calibration. Its low-power design uses two replaceable batteries and can operate for around 5 years under the specified SF7 conditions, making it suitable for long-term indoor monitoring.
