Milesight VO-AM319 Indoor Climate Sensor

Milesight VO-AM319, the LoRaWAN indoor climate sensor measures CO2, temperature, humidity, PIR motion, light, TVOC, air pressure, formaldehyde and particulate matter, with 4.2-inch display 

The Milesight VO-AM319 is the LoRaWAN indoor climate sensor that measures humidity, CO2, room temperature, PIR motion, light, TVOC, air pressure, formaldehyde and particulate matter. It was developed for wireless monitoring of indoor air quality and reliably transmits the measurements via the LoRaWAN standard to a separately available gateway. The data then goes to the cloud and can be retrieved from anywhere with statistics.

The Milesight VO-AM319 is powered via USB Type-C with 5 volts and 1 ampere. Configuration is conveniently performed with an app via NFC directly using a smartphone. An LED status indicator provides a color-coded light signal based on the traffic light system to show the current air quality.

The Milesight VO-AM319 features a 4.2-inch black and white E Ink display. Measurement values can be read directly from the display. With the choice between light and dark mode, the display can be perfectly adjusted to user needs. The strong building penetration of the LoRaWAN protocol also allows reception in basements. The sensor is designed for indoor use and has an IP30 protection rating. It is supplied with mounting accessories and can be discreetly mounted on the wall.

The Milesight VO-AM319 is the ideal solution for offices, classrooms, conference rooms, hotels, and all environments where good indoor air quality is essential. With Milesight Cloud, you can view data online, retrieve statistics, and activate switches if necessary. The connection is possible both via PC and on the go using the app. The sensor supports OTAA and ABP mode of Class C and is compatible with the EU868 frequency bands as well as other optional bands.
