Wireless Data Acquisition System - LoRa Gateway BL280
1 Product Introduction
1.1 General Introduction
Wireless Data Acquisition System BL280 is based on LoRa RF technology. It’s mainly used for
collecting multiple environmental data distributed in different long range areas and transparent data
transmission from device to cloud. With LoRa modulation technology, it’s capable of realizing
multiple IO device monitoring, collecting data of temperature & humidity, light intensity, CO2, wind
direction & speed and soil conditions.
LoRa communication range is up to 2KM.Built-in LoRa chip SX1278 and GSM/GPRS/3G/4G/RJ45
module work together to achieve remote monitoring and control by sending sensor, PLC, smart
meter and other device data to cloud or mobile phone via SMS/2G/3G/4G/Ethernet. Huge field
wiring cost will be saved
This wireless data acquisition system comprised of 2 parts, LoRa Gateway BL280 and LoRa Nodes.
Nodes connect senor, PLC and other devices. The collected data is sent to gateway. Mutual
communication between PLC and cloud is done through wireless RF technology. Alarm threshold
can be set in gateway so that alarm events can be recorded.

monitoring software or cloud for two-way communication through GPRS/3G/4G and Ethernet.
Below are the options:
1) Modbus RTU Protocol, i.e. Modbus RTU over TCP, transfer Modbus RTU protocol in TCP link to
realize two-way communication between gateway and host computer. For example, input cloud
platform WWW.MY-M2M.COM, Domain name: modbus.dtuip.com, port: 6651
2) Modbus TCP protocol, i.e.add TCP to the beginning and end of standard RTU protocol message
to realize two-way communication between gateway and host computer. For example, input cloud
platform WWW.MY-M2M.COM, Domain name: mbtcp.dtuip.com, port: 6655
3) MQTT protocol, i.e. execute MQTT protocol in TCP link to realize two-way communication
between gateway and host computer. The advantage of MQTT is data will be saved in cache if
network is lost and re-transmitted once network recovers. For example, input cloud platform:
WWW.MY-M2M.COM, Domain name: mqtt.dtuip.com, port: 1883
