Used to limit the current size. It creates a voltage drop by impeding the flow of electrons, following Ohm's law (V=IR). According to the material, it can be divided into carbon film, metal film, wire wound and other types. The parameters are marked by resistance (ohms, Ω) and power (watts, W), which play the roles of voltage dividing, current limiting, and load matching in the circuit.
A current protection device. When the current in the circuit exceeds the rated current of the fuse, it will melt due to overheating, thereby cutting off the circuit and preventing serious consequences such as fire and damage to electrical equipment due to overload or short circuit. Fuses are made of metals or alloys with lower melting points, and different specifications correspond to different rated currents. Fuses with specifications such as 10A and 15A are commonly used. When selecting a fuse, you need to select it based on the normal operating current of the circuit to ensure that its rated current is slightly greater than the normal current of the circuit to ensure safe and stable operation of the circuit.
A sensor is a device or device that senses, detects, or measures physical, chemical, or biological quantities and converts them into signals that can be processed (such as electrical signals, digital signals, etc.). It is a key component in modern automation, industrial control, Internet of Things (IoT), medical health, environmental monitoring and other fields. Its core function is to convert non-electrical signals (such as temperature, pressure, light intensity, sound, humidity, gas concentration, etc.) into electrical signals or other forms of signals to facilitate subsequent signal processing, transmission and analysis.
