Overview
AM308 overview
Core Purpose
The AM308 is designed to monitor indoor environmental quality in shared spaces. It helps organisations 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 centralised 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.
