Overview
AM103 is an indoor ambience monitoring sensor designed to track temperature, humidity, and carbon dioxide levels in real time. It helps users understand indoor comfort and air quality at a glance, making indoor environments healthier and more comfortable. The device is built for continuous monitoring without frequent maintenance.
The sensor shows live readings directly on a low-power E-ink screen, allowing occupants to quickly check indoor conditions without using software. Visual emoticons and a traffic light indicator make it easy to understand comfort levels and CO₂ status. This supports fast awareness even for non-technical users.
AM103 transmits sensor data wirelessly using LoRaWAN, enabling long-range communication with very low power use. It stores historical records locally and supports data retransmission to prevent information loss. This ensures reliable monitoring even if the network connection is temporarily unavailable.
The device operates on two replaceable batteries and is designed for long-term use, lasting multiple years without replacement. A smart screen hibernation mode further reduces power consumption. This makes AM103 suitable for long deployments with minimal upkeep.
AM103 supports easy setup through built-in NFC, allowing quick configuration via a mobile app. Sensor data can be managed remotely through Milesight’s platforms, reducing the need for on-site maintenance. This simplifies large-scale deployments across multiple locations.

Applications
AM103 helps maintain comfortable and productive indoor environments by monitoring air quality and climate conditions. Real-time visibility allows facility teams to respond quickly to poor ventilation or discomfort.
In classrooms and campuses, the device supports healthier learning environments by tracking CO₂ levels and indoor comfort. Visual indicators help staff recognise when ventilation is needed.
AM103 supports indoor air quality monitoring in hospitals and clinics, where comfort and proper ventilation are essential. Continuous monitoring helps maintain safer indoor conditions for patients and staff.
The sensor helps stores and public venues maintain pleasant indoor environments for visitors. Easy-to-read displays allow staff to monitor conditions without technical tools.
