Power selection of the LoRa module in different application scenarios

The LoRa module is a wireless communication module widely used in the Internet of Things, and its power selection depends on the specific application scenarios and requirements. Here are some key information from on search results:

1. The relationship between transmission distance and power

The transmission distance of the LoRa module is closely related to its power. Generally speaking, the greater the power, the farther the transmission distance. However, this does not mean that the maximum power should always be chosen to obtain the longest transmission distance. In fact, the selection of power needs to take into account the power consumption, transmission rate, power consumption and other factors. When selecting a module, you need to decide the appropriate power according to the actual use scenario.

2. The importance of anti-interference properties and sensitivity

The anti-interference and reception sensitivity of the LoRa module are also factors to be considered when selecting power. High sensitivity means that the receiving device can receive the signals transmitted remotely at a lower signal strength, thus improving the reliability and coverage of the communication. In addition, strong anti-interference can reduce the number of gateways required and reduce construction and maintenance costs.

3. Power consumption and product service life

For devices that require battery power, it is very important to choose a low-power LoRa module. This can not only save energy, reduce heat, thus extending the service life of the product, but also reduce the cost and trouble of replacing the battery. When selecting modules, the actual working environment and the expected service life of the product.

4. Influence of application scenarios

The power requirements of LoRa modules are different in different application scenarios. For example, when collecting data in a smart farm, the module with short communication distance can be selected, while in the factory environment, it is necessary to choose the size of the plant area. In some complex environments, such as mountains, jungles, lakes, further communication distance may be required, so it is necessary to choose a LoRa module with greater output power.

5. The relationship between baud rate and power

 The working frequency and port rate of the LoRa module can also affect its power consumption. Typically, higher baud rates can lead to greater power consumption. Therefore, selecting power requires balancing the demand of data transmission speed and power consumption.

In conclusion, selecting the power of LoRa module requires a comprehensive consideration of factors such as transmission distance, anti-interference, reception sensitivity, power consumption, product life, application scenarios and so on. In the practical application, the appropriate choices should be made according to the specific needs and conditions.
