AM308 Description

Core Purpose

The AM308 is designed to monitor indoor environmental quality in shared spaces. It helps organizations understand comfort, air quality, and occupancy conditions using a single, compact device. Information is shown locally on the screen and sent wirelessly for remote access.

Connectivity and Communication

The device uses LoRaWAN® to transmit data over long distances with low power use. This allows stable reporting through standard gateways and easy integration into centralized platforms. Data can be accessed and managed remotely without on-site intervention.

Monitoring and Detection Capabilities

AM308 measures temperature, humidity, CO₂, light, air quality indicators, airborne particles, and motion. These readings provide a clear picture of indoor comfort, air cleanliness, and space usage. Built-in indicators and a buzzer give instant alerts when thresholds are exceeded.

Display and Local Interaction

A large E-ink screen shows real-time values and comfort status using clear symbols. Multiple display modes make information easy to understand at a glance. Physical buttons allow simple local control and configuration.

Power and Environmental Suitability

The device can run on replaceable batteries or USB-C power, offering flexible installation. It is built for indoor environments and operates reliably across typical indoor temperature and humidity ranges. Local storage protects data during network interruptions.

Industry Applications

AM308 Industrial Applications

Commercial Offices

AM308 helps maintain comfortable and healthy workplaces by tracking air quality, temperature, and occupancy trends. This supports better ventilation decisions and employee well-being.

Education Facilities

In classrooms and lecture halls, the sensor provides visibility into CO₂ levels and comfort conditions. This helps schools improve learning environments and manage crowded spaces.

Healthcare Buildings

Hospitals and clinics use AM308 to monitor indoor air quality and comfort in patient and staff areas. Continuous tracking supports healthier indoor conditions.

Retail and Public Spaces

Stores and public buildings benefit from real-time insight into comfort and occupancy. This helps improve visitor experience and supports energy-aware facility management.
