LoRa is a low-power WAN communication technology with promising prospects. It has been widely used in various fields of the Internet of Things. It can be seen that the LoRa communication module occupies an important position in the Internet of Things industry. Although the development prospect of LoRa wireless module is very good, it has its advantages and disadvantages as a technical product, and which application fields are applied to analyze it one by one.
Advantages of the LoRa module
1, low power communication distance is far. The sensitivity of the LoRa communication module is -139 dBm and the communication distance is more than 7000 kilometers, which solves the problem that low power consumption and long distance cannot be combined.
2, easy to build and deploy, free license plate band nodes. The price of the LoRa module is very close to the people and will play a huge advantage in all major areas of the Internet of Things.
Disadvantages of the LoRa module
1. Spectrum interference. LoRa's development momentum is very good, and LoRa equipment and network deployments are increasing, and there will be certain spectrum interference between them.
2. You need to create a new network. During the deployment of LoRa, new signal towers, industrial base stations and even portable home gateways are needed.
Which application areas does the LoRa module apply to?
1. Smart wireless meter reading: The LoRa communication module is widely used in smart wireless meter reading. The data collection device of the distribution box transmits the power consumption information of each household to the LoRa module, and the LoRa module transmits the data through the gateway. Give the remote control center. The advantages of low power consumption and low cost of the LoRa module are more conducive to large-scale promotion and help to develop smart cities.
2. Agricultural informatization: comprehensive development and application of modern network technology in the agricultural field, making agricultural production more convenient, effectively reducing costs and increasing production.
LoRa realizes the interconnection of agricultural nodes, with low power transmission distance and no communication cost, making it a reality in large-scale application of agricultural production. For example, in the detection of water quality, temperature, humidity, carbon dioxide concentration, pests and diseases, the collection equipment information can be transmitted to the control dispatching center through the LoRa module, according to real-time data analysis, automatic irrigation, automatic spraying and other measures.
All in all, the LoRa communication module has the advantages of low power consumption, long distance, high sensitivity and strong anti-interference, making it widely used in IoT agriculture, smart wireless meter reading, robot control, security system, vehicle tracking, and smart city. The future of LoRa technology is developing more broadly.
