A voltage sensor for Smart Home is a device that is used to monitor the voltage levels in the electrical system of a home. It can detect and measure the voltage of the power supply, and can alert the homeowner if there are any fluctuations or abnormalities in the voltage levels. This can help prevent electrical issues and potential damage to appliances or devices in the home. Additionally, some voltage sensors can be integrated with smart home systems to provide real-time monitoring and notifications to the homeowner's smartphone or other smart devices. **
