AM307 Milesight LoRaWAN Sensor

Core Purpose

AM307 is an indoor ambience monitoring sensor designed to help people understand comfort and air quality inside buildings. It continuously measures key environmental conditions and shows the results directly on a clear E-ink screen. This makes indoor conditions easy to read without needing a phone or computer. The device is built for shared spaces where comfort, health, and awareness matter. It works quietly in the background while providing clear visual feedback to occupants and facility teams.

Connectivity and Communication

AM307 uses LoRaWAN for long-range, low-power wireless communication. This allows it to send sensor data reliably to a central platform without complex wiring. The device works with standard LoRaWAN gateways and network servers. Data can be viewed and managed remotely through Milesight platforms, making it easy to monitor many locations from one place. Local data storage and retransmission help prevent information loss if the network is temporarily unavailable.

Monitoring Capabilities

AM307 monitors indoor temperature, humidity, light level, CO₂, TVOC, barometric pressure, particulate matter (PM2.5 and PM10), and motion. Together, these measurements provide a clear picture of indoor comfort and air quality. Motion detection helps identify room occupancy status. A built-in traffic light indicator, buzzer, and screen emoticons give instant visual and audible alerts when conditions cross set thresholds. This allows quick awareness without needing to check software dashboards.

Display and Interaction

The 4.2-inch E-ink display shows real-time readings in a clean, easy-to-read format. Multiple display modes help users quickly understand comfort levels at a glance. Physical buttons allow basic interaction such as power and reset. Configuration can be done through NFC or USB, making setup and maintenance simple for installers and operators.

Power and Environmental Suitability

AM307 can run on replaceable batteries or a DC power supply, offering flexible installation options. Long battery life supports continuous operation with minimal maintenance. The device is intended for indoor use and wall mounting in common environments such as offices or classrooms.
