Milesight AM series sensors measure indoor air quality — CO2, temperature, humidity, TVOC, PM2.5, and more. These connect to Vemcount as IoT data sources and display via the Realtime IoT widget, enabling combined dashboards showing both footfall and environmental data on the same screen.
AM102 / AM102L | 2-in-1 IAQ sensor. CO2 + temperature + humidity. Compact wall-mount. LoRaWAN or PoE. Best for meeting rooms and small offices. |
AM103 / AM103L | 3-in-1 IAQ sensor. CO2 + temperature + humidity + barometric pressure. LoRaWAN or PoE. |
AM300 Series | All-in-1 IAQ sensor. Up to 7 parameters: CO2, temperature, humidity, TVOC, PM2.5, light, barometric pressure. Built-in e-ink display. LoRaWAN or PoE. Best for open offices, schools, and any space where air quality visibility matters. |
CO2 | ppm — carbon dioxide concentration. Alert when above 1000ppm (typical office threshold). |
Temperature | °C or °F |
Humidity | % relative humidity |
TVOC | Total volatile organic compounds — air quality index |
PM2.5 | Fine particle matter — air quality for health monitoring |
Light level | Lux — ambient light intensity |
Barometric pressure | hPa |
Display | Built-in e-ink screen showing real-time readings locally |
Connectivity | LoRaWAN or PoE · HTTP(S)/MQTT(S) |
Power | PoE (802.3af), USB-C, or battery (model dependent) |
Mounting | Wall mount (comes with bracket) |
Operating temp | -10°C to 60°C |
Certifications | CE, FCC, RoHS |
Register the sensor in Vemcount: ⚙ Settings → Devices → + Add sensor → enter DevEUI (LoRaWAN) or MAC address (Ethernet) → Vendor: Milesight → submit.
Ensure data is flowing: check Settings → Devices → confirm sensor shows green (online).
On your dashboard, click + → Widget → Realtime.
Select Source Type → choose the AM sensor → select the metric (CO2, Temperature, Humidity, etc.).
Give the widget a clear title (e.g. "Meeting Room A — CO2") and save.
Optionally add a widget alert (three-dot menu → Alerts → + Add alert → Max value → e.g. 1000 ppm → WhatsApp or email action) to be notified when CO2 exceeds safe levels.
Combined dashboard tip: Put an AM300 CO2 widget, a Live Inside occupancy widget, and a visitors chart widget on the same dashboard for a complete smart office view. When CO2 rises alongside high occupancy, you know ventilation is needed. This is a strong Vemcount use case for office and education customers.
< 600 ppm | Excellent — fresh outdoor air level |
600–1000 ppm | Good — typical well-ventilated office |
1000–1500 ppm | Moderate — consider increasing ventilation |
> 1500 ppm | Poor — open windows or activate HVAC. Alert threshold recommended. |
