Before answering this question, let's briefly understand what sensitivity is. Receiving sensitivity is a very important parameter in a wireless module, which is a negative value.wireless module The smaller the negative value, the higher the reception sensitivity. Sensitivity is effective only when the data is received by the wireless module, so it is also called reception sensitivity.

We teachers can analyze the sensitivity as an analogy to human hearing ability. When our hearing is more sensitive, we are able to hear the sound of China farther or smaller by ourselves; similarly, in the wireless field, the transmission security distance is getting farther and farther, the signal is relatively weaker and weaker. Receiving system sensitivity problem is like a our hearing teaching, when the higher the sensitivity requirements,smart module can be through the reception of the weaker signal. Therefore, in the wireless field, when the sensitivity index is higher, also represents a longer distance.

So, is higher sensitivity better? For this reason, we need to judge according to the specific project and working environment. Although the sensitivity value is determined internally by the chip and cannot be changed, it is not a fixed value. When we modify the transmission rate of the wireless module, the sensitivity value will fluctuate. The higher the speed, the lower the sensitivity; the lower the speed, the higher the sensitivity. Therefore, the sensitivity value is different at different rates.

Generally speaking, when choosing a wireless module, we need to consider the needs of the project and the working environment. Although sensitivity is an important parameter, it is not the only deciding factor. When selecting a wireless module, we need to consider various factors to ensure that the wireless module can meet the needs of the project.
