Indoor Air Quality Monitoring Sensors - LoRaWAN®, CO2, PM and Multi-Parameter Measurement: AM307 / AM308 / AM319 | Milesight

The LoRaWAN® indoor air quality and ambience monitoring sensors - comfort, CO2 and particulate monitoring: AM307 / AM308 / AM319 are designed for continuous indoor environmental monitoring in offices, classrooms, healthcare facilities, commercial buildings, laboratories and smart building applications.

The range covers several levels of indoor air quality monitoring. The AM307 is intended for core comfort and IAQ parameters, the AM308 adds particulate matter measurement, and the AM319 provides an advanced configuration with optional HCHO or O3 monitoring depending on the selected PN.

Data is transmitted through LoRaWAN®, enabling integration with standard LoRaWAN® gateways and remote monitoring platforms. The local E-Ink display, traffic light status indicator and buzzer provide direct on-site visibility of indoor conditions and threshold alarms.
