Milesight - AM103 & AM103L
Indoor Ambience Monitoring Sensor

The Milesight AM100 Series Indoor Ambience Monitoring Sensor is an indoor ambience sensor for measuring temperature, humidity and CO2. The AM103 features a E-ink screen with light and dark colour themes, while the AM103L has a longer battery life. Common use cases include offices, classrooms and hospitals.

Ensure comfort at any moment with 3 sensors in 1 to accurately track the invisible elements of the air. This one stop solution for measuring indoor air quality to ensure comfortable and healthier facilities can be achieved from the AM100 Series. Use hibernation mode to extend battery life when not using the sensor. Pause data collection whilst in hibernation to monitor data collection rates. This creates an energy efficient solution that also improves productivity and satisfaction.

The AM103 and AM103L have a data transmission range of 15km in rural areas and 2km in urban environments. This makes the Milesight Indoor Ambience Monitoring Sensor compatible with various industry-standard LoRaWAN gateways.
