Milesight AM319 LoRaWAN Indoor Air Quality Sensor (9 in 1)

The Milesight AM319 is a compact indoor ambience monitoring sensor that collects various indoor air quality conditions through 9 built-in sensors and delivers the data to mobile apps and its 4.2-inch E-ink screen. It measures temperature, humidity, CO2 concentration, TVOC, barometric pressure, light, PIR motion, PM2.5, and PM10. The device supports battery or DC power supply and can be easily configured via NFC. It features a tri-color LED indicator, buzzer for threshold alarms, anti-theft design, and emoticon indication on the display. The AM319 is widely used for offices, stores, classrooms, hospitals, and other commercial buildings.

Thinger.io Integration

The Milesight AM319 integrates seamlessly with Thinger.io through LoRaWAN network servers, enabling real-time monitoring, data visualization, and remote management of indoor air quality parameters.

Requirements

A LoRaWAN server is required to communicate the Milesight AM319 into Thinger.io. Some options are:

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed, a new Product will be created for this device.

Configuration

The Product is already preconfigured. Check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your preference. Configure the device using NFC via the Milesight ToolBox mobile app for quick LoRaWAN parameter setup.

Usage

Start sending uplinks for autoprovisioning devices and buckets. This product provides access to all 9 sensor readings including temperature, humidity, CO2, TVOC, barometric pressure, light, motion detection, PM2.5, and PM10. The platform also supports predefined dashboards for comprehensive air quality monitoring and downlinks for device configuration.
