DFRobot May 04 2023 1884

LoRa, as a low-power, long-range, cost-effective, and efficient wireless digital communication technology, has been widely used in smart metering, logistics tracking, smart campus, industrial parks, and medical services, and has unique advantages in specific fields.

With the process of urbanization and industrialization, the construction of basic infrastructure such as water and electricity is also becoming more and more perfect. The LoRa remote meter reading system consists of equipment layer composed of instruments such as water meters and electricity meters, acquisition layer composed of LoRa gateway, and application layer composed of upper computer and cloud platform. Through the protocol analysis of the equipment, the LoRa gateway can collect real-time data generated by the equipment, and after data processing, the data can be uploaded to the terminal device in the hands of the manager. The whole process does not require manual operation or going out, just check the data report and export data information to complete the work, which is very easy.

Traditional manual meter reading faces problems such as a large number of water meters, wide distribution, large manual transcription errors, and difficult management and maintenance. However, the LoRa gateway remote data acquisition can play a great advantage due to its simple networking, large node capacity, long transmission distance, and other characteristics.


2. Real-time Logistics Vehicle Tracking

Logistics tracking is actually the management of the information flow in logistics. IoT solutions based on LoRaWAN can help supply chain and logistics companies monitor the real-time status of goods transportation. Due to the long distance and long time required for logistics transportation, the system responsible for location tracking needs to have the advantages of low power consumption and network stability. From warehouses to transportation vehicles, even to every piece of goods, a positioning system with a LoRa module can be added.

LoRa has low power consumption and relatively stable communication when moving at high speeds, allowing it to track and determine the location and status of goods in real-time. During transportation, it can provide stable network coverage and transmit real-time data of goods, whether in cities or sparsely populated suburbs.

LoRaWAN-based smart classroom solutions connect various educational devices, such as temperature sensors, humidity sensors, lighting systems, window controllers, access control systems, and more. By connecting these devices to a cloud platform, teachers and administrators can monitor and control the status of the classroom in real time, as well as perform data analysis and management. For example, predefined scene commands can be used to control lighting, air conditioning, curtains, projectors, and other devices in batches. In teaching, teachers can define various scenarios, such as courses, breaks, dismissals, lunches, multimedia, quiet study, etc. Teachers and students can control all devices with one press to adapt to specific scenarios.

LoRa technology-based smart classroom solutions improve classroom comfort while also enhancing teaching efficiency. LoRaWAN gateways support seamless interoperability between smart devices, with simple deployment and wireless batch deployment that can be quickly replicated from a pilot to all classroom environments, greatly reducing deployment costs and manual construction costs.


4. Farm environment monitoring

Based on LoRa, smart farms can monitor soil and climate conditions in real-time, analyze the carbon dioxide, light intensity, nutrients, temperature, and humidity needed for crops, and achieve optimal growth conditions. When setting up such a system, the following factors need to be considered: Wiring can be complicated due to the outdoor farm environment; Real-time and accurate data is required to meet the needs of crop growth.

LoRaWAN gateways provide the following advantages in this application scenario: wireless networking reduces wiring costs; stable signals enable real-time monitoring of environmental conditions, reducing on-site operating costs. LoRa technology is increasingly being used in traditional agriculture, and smarter farming methods are emerging.


5. Industrial Park Monitoring

Smart industrial parks use LoRa gateways to link with various sensors such as temperature and humidity sensors, PM2.5 sensors, and current sensors. The terminal data is uploaded to the LoRa gateway, which then transmits the data to the cloud through multiple communication methods. The cloud platform uses big data analysis to display the real-time situation of the park based on the collected data. If there is any risk, an automatic alarm will be triggered. After receiving the alarm information, management personnel can remotely control the on-site equipment or arrange personnel to dispose of the problem in a timely manner to minimize losses.

LoRa has strong anti-interference ability and high sensitivity, making it very suitable for industrial park scenarios with complex electromagnetic environments.


6. Smart Infusion Management

By automatically collecting infusion equipment and patient data, timely alerts can be sent for abnormal information. Then, the data is uploaded to the nurse station monitoring main screen through the LoRa gateway. This way, medical staff can obtain real-time information on patient infusion status and information through the big screen no matter where they are in the ward. The entire infusion process is included in remote intelligent monitoring, which reduces the frequency of bedside rounds and improves the efficiency of nursing work, while reducing the risk of medical accidents.

Based on the "wireless self-organizing, security, and controllability" characteristics of LoRa IoT technology, the smart infusion terminal combined with sensors and LoRa technology can collect data on the infusion process without the need for wiring or ward renovation.


Summary

LoRa has been widely used in remote data acquisition, agricultural environment monitoring, and logistics tracking, as well as providing solutions for campuses, parks, and medical services. As the application scope of LoRaWAN technology continues to expand, market demand will also increase accordingly. Especially in the fields of smart cities, smart logistics, and smart agriculture, the application of LoRaWAN will continue to grow.
