Embodiment Construction
[0029] During specific implementation, the hardware design of the temperature acquisition module is as follows: figure 2 , the module is powered by a battery (①), and the battery uses a rechargeable lithium battery. When the battery is dead, it can be charged and recycled. The temperature sensor DS18B20 (②) collects the temperature of each node, and the MCU controls it as a low-power chip (③). It is responsible for converting the data collected by DS18B20 (②), and the converted data is transmitted through the NRF905 (④) wireless module. Each slave module has a different address, so the temperature displayed by the main controller when having different address temperatures.
[0030] During the specific implementation, the software design of the temperature measurement module is as follows: Figure 4 , including the design idea and process of the software, the self-test of the temperature sensor when it is powered on, if it is normal, it will detect the normal temperature, i...
