MILESIGHT - LoRaWAN air quality sensor TVOC/CO2/HCHO/PM2.5/PM10 AM319

Improving energy efficiency and indoor comfort

The AM319 is a compact indoor environment monitoring sensor that measures temperature, humidity, light, CO2 concentration, HCHO/O3 level, TVOC, barometric pressure, PM2.5, PM10 and movement. Data is displayed in real time on the E-ink screen, enabling indoor environment and comfort to be measured. The AM300 series is widely used in offices, stores, classrooms, hospitals, etc.

Sensor data are transmitted using LoRaWAN technology. By combining Milesight's LoRaWAN gateway and Milesight's IoT Cloud, users can manage all sensor data remotely and visually.

Features of the MileSight AM319 air quality sensor

• Integrated with multiple sensors such as humidity, temperature, CO2, light, barometric pressure, PM2.5, PM10, etc.
