Milesight IOT - Indoor Ambience Monitoring Sensor (7 in 1)

The AM307 is a compact sensor for monitoring indoor environment, measuring temperature, humidity, light, CO2 concentration, TVOC, barometric pressure, and movement. Data is displayed in real-time on the E-Ink screen, aiding in measuring indoor environment and comfort. The AM307 is widely used in offices, shops, classrooms, hospitals, etc.

Sensor data is transmitted using LoRaWAN ® technology. When paired with a Milesight LoRaWAN ® gateway, users can manage all sensor data remotely and visually.

Features

• Integrated with multiple sensors such as humidity, temperature, CO2, light, barometric pressure, COVT, etc.
• Multiple display modes and clear emojis to easily understand comfort levels via the screen.
• Equipped with a traffic light indicator and a buzzer to display device status and threshold alarms.
• Battery support.

7 integrated sensor types to measure various environmental conditions

• Temperature
• Humidity
• PIR
• Light
• TVOC
• Barometric Pressure
• CO2

Greater accuracy through improved isolation design

The location of temperature and humidity sensors is designed to isolate the heat generated when the chip operates.

More features with a larger screen

The AM307 environment control sensor is equipped with a 4.2-inch E-Ink screen that can display real-time environmental conditions in various ways.

Smart screen mode

When the PIR value is 0 (unoccupied) and persists for 20 minutes, the screen stops refreshing to save energy.

Based on LoRaWAN

• Penetrating signals: Data transmission range up to 2 KM in urban areas and 15 KM in rural areas.
• High compatibility: Compatible with standard LoRaWAN® gateways and network servers.

Storage capacity with 18,000 historical data sets

Data can be stored in the device and cannot be manually deleted, increasing the traceability of reported information.

Support for retransmission for reliable communication

By supporting data retransmission, the device ensures that the web server receives all data, even if the network is occasionally down.
