9-in-1 IAQ Sensor AM308L-868M – Milesight AM308L

The Milesight AM308L-868M is a multi-sensor IAQ (indoor air quality) node built for scalable, data-driven air quality monitoring across buildings. It combines key parameters in one device to support better ventilation decisions, comfort management, and energy efficiency—especially in offices, schools, and public facilities.

This listing specifically covers the AM308L-868M (EU868) variant without the 4.2-inch E-ink screen, making it a strong fit for deployments where readings are visualized centrally rather than on-device, and where a streamlined rollout is preferred. Typical use cases include CO2-driven ventilation, humidity/temperature monitoring to reduce comfort complaints and moisture risk, and particulate/VOC insight for healthier indoor environments.

For data reliability and traceability, the device supports data storage (18,000 entries), data retrievability, and data retransmission to reduce the impact of temporary network outages. Threshold alarms can be used to trigger alerts when CO2, PM, or other metrics exceed acceptable limits. Local indication is supported via a traffic light status indicator and buzzer, and a button lock helps prevent unwanted interaction.

Power options include four replaceable Li-SOCl2 batteries or USB-C (5V/1A), useful for fixed powered installations or commissioning/service access.

Typical deployments: classrooms, meeting rooms, open-plan offices, hot-desking areas, waiting areas, libraries, healthcare facilities, and building automation environments.
