Two important insights can be shared to the research communities of Internet of Things (IoTs), Wireless Sensor Networks (WSNs), reliability and security:
1) Without a special design in hardware configuration for protection, WSNs node should not be deployed nearby devices that can release high-voltage pulse discharge, e. g., SIL;
2) The above type of devices can be used as a malicious method to attack WSNs, leading to abnormal working state.
