Milesight IOT- Lorawan 9 in 1 air quality sensor (Option: HCHO)

The AM319-HCHO is a compact sensor for monitoring the indoor environment including motion, humidity, temperature, light, TVOC (Total Volatile Organic Compounds), CO2 (Carbon Dioxide), HCHO (Formaldehyde), barometric pressure and PM2.5 and PM10. It is equipped with NFC (Near Field Communication) and can be easily configured via a smartphone or PC software.

Sensor data is transmitted in real time using the standard LoRaWAN® protocol. LoRaWAN® enables encrypted radio transmissions over long distances, consuming very little energy. The user can obtain the sensor data and visualise the progress of the data change via the Milesight IoT Cloud or through the user's network server.

• PM2.5 AND PM10

 

Greater accuracy with better insulation design

The positioning of the temperature and humidity sensors is designed to isolate the heat generated during chip operation.

Superior sensor with strong resistance to interference

The selection of the HCHO sensor is dedicated to reading stability, particularly with regard to alcohol resistance.

 

More functions with a larger screen

The AM300 environmental monitoring sensor is equipped with a 4.2-inch E-ink screen to display real-time environmental conditions in many ways.

 

Intelligent screen mode

When the PIR value is 0 (empty) and lasts 20 minutes, the screen stops updating to save power.

 

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® network gateways and servers.
• Storage capacity with 18000 sets of historical data records
• Data can be stored in the device and cannot be manually deleted, further ensuring traceability of reported information.

 
Retransmission support for reliable communication

With support for data retransmission, the device ensures that the web server receives all data even if the network is occasionally interrupted.
