Description
AM308 series is a compact indoor ambience monitoring sensor for measurement of temperature, humidity, light, CO2 concentration, HCHO/O3 level, TVOC, barometric pressure, PM2.5, PM10 and motion. The data will be shown on the E-ink screen in real-time, which helps to measure the indoor environment and comfort. AM308 series is widely used for offices, stores, classrooms, hospitals, etc.
Sensor data is transmitted using LoRaWAN ® technology. Combining Milesight LoRaWAN® gateway and Milesight IoT Cloud, users can manage all sensor data remotely and visually.
Main Features
- Robust LoRaWAN® connectivity for indoor or HVAC environments
- Integrated multiple sensors like temperature, humidity, light, air quality, etc.
- Easy configuration via NFC
- Multiple display mode and clear emoticon on the e-ink screen
- Equipped with traffic light and buzzer to indicate threshold
- Standard LoRaWAN® supported
- Milesight IoT Cloud compliant
- Battery or DC power supply
Ensuring Indoor Comfort and Health
9 Sensors in 1
Integrated 9 types of sensor to measure various ambience conditions
- Temperature
- Humidity
- PIR
- Light
- TVOC
- Barometric Pressure
- CO2
- O3
- PM2.5 & PM10
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.
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 15 KM 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.
Easy Configuration
Switching on/off and configuring the device via NFC technology from mobile phone or PC
