The following table is a comparison table of the application conditions of the above examples and comparative examples

The following conclusions can be drawn in the case of combining the above examples and comparative examples:

1. when both temperature sensors are in the same environment, temperature difference is difficult to form, so that the power supply only provides power for monitoring and the like in comparative example 1;
