Power sensors measure electrical power by converting the energy into a readable signal. They typically work by detecting voltage and current, then multiply these values to provide power in watts. Two common types are thermal sensors, which detect heat produced by power, and diode-based sensors, which use semiconductor properties. These sensors are essential in monitoring and managing energy consumption in various applications, from household appliances to industrial machines.
