How to choose a suitable low-power LoRa module

By sdga:NiceRF Wireless Technology Co., Ltd

LoRa is a kind of low-power wide-area network communication technology. It is an ultra-long-distance wireless transmission scheme based on spread spectrum technology adopted and promoted by Semtech of the United States. The continuous development of LoRa technology makes the LoRa module more perfect, and how to choose a suitable low-power LoRa module has also become a problem. This article will introduce the functional characteristics of low-power LoRa modules, to select low-power LoRa modules suitable for wireless meter reading and industrial control.

1. Low power consumption of LoRa module

For wireless meter reading and industrial control, the LoRa module is used for data transmission and data control through the wireless terminal. We all know that most of the equipment that requires battery power is to be used for a long time. Of course, the lower the power consumption, the better, which can save power. The low-power LoRa module's sleep currently is below 0.2uA, which can ensure the long-term use of the battery.


2. Long transmission distance

The LoRa module has a long communication distance, and the open transmission distance is more than 5000 meters, which solves the problem of low power consumption and long-distance. It is suitable for projects that require ultra-long distance communication.


3. Strong anti-interference ability

The LoRa module adopts LoRa wireless spread spectrum technology with ultra-high receiving sensitivity of -139dBm, which has better penetrating power than traditional GFSK and FSK modules, greatly reducing the number of gateways and construction costs.

In summary, these features are available in a LoRa module today. There are many LoRa modules on the market, but the module parameters of different manufacturers may be different, and the materials used are also different. It is difficult to guarantee that the LoRa modules purchased are high-quality and suitable modules. NiceRF Wireless's LoRa1278 and LoRa1276, the sleep current of these two LoRa modules is less than 0.2uA, and the open transmission distance is 5000 meters, low power consumption and long-distance can meet the application of industrial and wireless meter reading.
