AM103 is a compact indoor ambience monitoring sensor for measurement of temperature, humidity and CO2. These data will be shown on the E-ink screen in real-time, which allow to quantify the indoor environment and comfort. AM103 is widely used for office, store, classroom, hospital, etc.

Apart from screen display, sensor data can also be transmitted using LoRaWAN®. With this low-power technology, AM103 can work for more than 3 years with 2 replaceable batteries. Combining with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, users can manage all sensor data remotely and visually

AM103 LoRaWAN IAQ Sensor

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 (tem ≤ ±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 × 2700mAh ER14505 Li-SOCL2 replaceable batteries ensure more than 3 years’ service life.
