Milesight 47,000 LoRaWAN® IAQ Sensors in Canadian Schools
With province-wide LoRaWAN® IAQ solution deployment, students and staff in Quebec's public schools are now in a healthier learning environment with more helpful insights. Check how Milesight has made it happen!

Clearer View of CO2 Concentration and Temperature
In the upgraded display mode of the AM103, the values of CO2 concentration and temperature are bolded in a larger space.
Indoor Air Monitoring (IAQ) Solution
At Milesight, we help you and your people to live in a safer and healthier facilities. Towards that end, real-time data about air quality is essential. And that starts with our one-stop solution for indoor air quality (IAQ)
Smart Screen Mode for Energy-Saving Operations
When the current collected value is close to the last value*, the screen will stop updating to save power.
– When the reading is within a certain range (temp. ≤ ±0.5°C and hum. ≤ ±3% and CO2 ≤ ±50 ppm).
— When Screen Smart Mode is enabled, the minimum refresh interval is customizable from 2 to 1080 minutes to refresh the screen.
Hibernation Mode for Ultra-Low Power Consumption
-Use hibernation when you know you will not be using the IAQ sensor for an extended period of time to save more power.
-Hibernation uses less power than smart screen mode because data collection will automatically turn off.
-Customers can turn on the LoRa uplink with hibernation mode enabled, in which case the screen will still keep displaying hibernation mode, but only to save screen power consumption.
Multi-Year Battery Operation
Built-in 2 × 2700 mAh ER14505 Li-SOCL2 replaceable
batteries ensure more than 3 years’ service life.
Energy Efficiency Solution
Everything from the way we operate to what we consume is moving toward more energy-efficient ways. Check how Milesight sensing products can help you.
