Problems solved by technology

figure 1 The circuit schematic diagram for the power supply part of the traditional agricultural environment monitoring system, from figure 1 It can be seen from the figure that the power supply part of the traditional agricultural environmental monitoring system uses many components, the circuit structure is complicated, the hardware cost is high, and it is inconvenient to maintain

In addition, due to the lack of corresponding circuit protection functions in the power supply part of the traditional agricultural environmental monitoring system, such as the lack of current limiting protection functions, the safety and reliability of the circuit are poor
