9 Sensors in 1
Integrated 9 types of sensor to measure
various ambience conditions
Higher Accuracy with
Better Insulation Design
Placement for temperature and humidity sensors is designed to isolate the heat generated when the chip is operating.
Superior Sensor with
Strong Anti-Interference
Selection for HCHO sensor is dedicated to stable reading, particularly in its resistance to alcohol.
More Features with Bigger Screen
The AM300 Ambience Monitoring Sensor equips with a 4.2 inch E-ink screen to show the real-time ambience conditions in many ways.
Multiple Display
Styles
Light/Dark Color
Theme
Low Power Consumption
Smart Screen Mode
When PIR value is 0 (Vacant) and last for 20 mins, the screen will stop updating to save power.
Multi-Year Battery Operation
*4 × 2700 mAh ER14505 Li-SOCl2 Replaceable Batteries
**AM307/AM308 can also be powered via Type-C.
LoRaWAN® Based
- Penetrating Signals: data transmission range up to 2 km in urban areas and 15km in rural areas
- High Compatibility: compliant with standard LoRaWAN® gateways and network servers
Store Capacity with 18000 Sets of Historical Data Records
Data can be stored in the device and cannot be manually deleted, further securing the traceability of the reported information.
Support Retransmission for Reliable Communication
With support for data retransmission,the device guarantees that the web server gets all the data even if the network is down occasionally.
