Note:
1. The power supply current must be greater than 30mA to drive the module, and the voltage must be stable without large fluctuations, otherwise it will cause continuous triggering (the load light may be continuously triggered by itself or not extinguished)
2. The product should not be installed next to a large-area metal body, and cannot be placed in a completely enclosed metal shell, which will affect the performance of this product or cause it to be unable to be used normally.
