The AM103 is a small indoor environmental monitoring sensor that measures temperature, humidity, and CO2. This information will be displayed on an E-ink screen in real-time, allowing for the quantification of the indoor environment and comfort. The AM103 is commonly used in offices, retail, classrooms, and hospitals, among other places.

Sensor data can also be transmitted using LoRaWAN, in addition to its screen display. With this low-power technology, the AM103 can last up to 3 years on two replaceable batteries. Users can manage all sensor data remotely and visually using the Milesight LoRaWAN gateway and Milesight IoT Cloud solution.

Key Features:

  • Integrated with multiple sensors like humidity, temperature and CO2
  • Visual data and clear emoticon to understand the comfort level easily via the E-ink screen
  • Equipped with traffic light indicator to indicate multi-level CO2 threshold alarms
  • More than 3 years of functioning without replacing batteries
  • Built-in NFC for easy configuration
