110x4, 5Vi500/FKM80 electrical components are detection devices that can sense measured information and convert the sensed information into electrical signals or other required forms of output according to specific rules, to meet requirements for information transmission, processing, storage, display, recording, and control. The existence and development of sensors give objects senses such as touch, taste, and smell, bringing them to life; sensors are an extension of human senses. Sensors feature miniaturization, digitization, intelligence, multifunctionality, systematization, and networking, making them the primary link in achieving automatic detection and automatic control. A device or apparatus that can sense a specified measured quantity and convert it into a usable signal according to a certain rule (mathematical function law), typically composed of a sensitive element and a conversion element.

LED lamps are light-emitting diodes, using solid-state semiconductor chips as the light-emitting material. Compared with traditional lamps, LED lamps are energy-efficient, environmentally friendly, and offer good color rendering and response speed. (1) Energy efficiency is the most prominent feature of LED lamps in terms of energy consumption; the energy consumption of LED lamps is one-tenth that of incandescent lamps and one-quarter that of energy-saving lamps. This is a major characteristic of LED lamps. People today advocate energy conservation and environmental protection, and it is precisely this energy-saving feature that makes the application range of LED lamps very wide and makes LED lamps very popular. (2) Can operate in high-speed switching states. When walking on the street, we find that every screen or image composed of LED is ever-changing. This indicates that LED lamps can perform high-speed switching operations. However, the incandescent lamps we usually use cannot achieve such an operating state. In daily life, if the switching frequency is too high, it will directly lead to the breakage of the incandescent lamp filament. This is also an important reason why LED lamps are popular. (3) Environmental protection: LED lamps do not contain any heavy metal materials such as mercury, whereas fluorescent lamps do, which reflects the environmental friendliness of LED lamps. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lamps. (4) Fast response speed is another prominent feature of LED lamps, namely, their fast reaction speed. As soon as the power is connected, the LED lamp lights up immediately. Compared with the energy-saving lamps we usually use, their response speed is faster. When turning on traditional bulbs, it often takes a long time to illuminate the room, and they only light up after the bulb has thoroughly heated up. (5) Compared with other light sources, LED lamps are "cleaner." The so-called "clean" does not refer to the cleanliness of the lamp surface and interior, but rather that this lamp is a cold light source, does not generate excessive heat, and does not attract insects that are attracted to light and heat. Especially in summer, there are many insects in rural areas. Some insects are naturally heat-loving; incandescent lamps and energy-saving lamps generate heat after being used for a period of time, and this heat is exactly what insects like, easily attracting them. This will undoubtedly bring many pollutants to the lamp surface, and insect excrement will make the indoor environment very dirty. However, LED lamps are cold light sources and do not attract insects, thus avoiding insect excrement. Therefore, LED lamps are "cleaner." Semiconductor light-emitting diodes have a wide range of applications, low power consumption, long service life, and are low-carbon and environmentally friendly. The application of semiconductor light-emitting diodes in China is very extensive; many lighting fixtures in residential homes use semiconductor light-emitting diodes, and most streetlights also use semiconductor light-emitting diode streetlights as lighting sources. Some road lighting fixtures also combine solar technology, saving a large amount of electrical energy. Photodiodes can be divided into gallium aluminum arsenide photodiodes, aluminum gallium phosphide arsenide photodiodes, gallium phosphide photodiodes, and aluminum arsenide photodiodes, depending on the material.

A solid-state relay consists of three parts: input circuit, isolation, and output circuit. According to different categories of input voltage, input circuits can be divided into DC input circuits, AC input circuits, and AC/DC input circuits. Some input control circuits also have functions compatible with TTL/CMOS, positive/negative logic control, and inversion, allowing convenient connection with TTL, MOS logic circuits. For control signals with fixed control voltage, resistive input circuits are used. The isolation and coupling methods between the input and output circuits of solid-state relays include optocoupling and transformer coupling: optocoupling typically uses photodiode-phototransistor, photodiode-bidirectional light-controlled thyristor, or photovoltaic cells to achieve isolated control between the control side and the load side; high-frequency transformer coupling utilizes the self-excited high-frequency signal generated by the input control signal, coupled to the secondary side, demodulated and rectified, and processed by logic circuits to form a drive signal. The power switch of the solid-state relay is directly connected to the power supply and load terminals to realize the on/off switching of the load power. Mainly used components include high-power bipolar transistors, unidirectional thyristors, bidirectional thyristors, power field-effect transistors, and insulated-gate bipolar transistors. The output circuit of a solid-state relay can also be divided into DC output circuits, AC output circuits, and AC/DC output circuits. According to the load type, it can be divided into DC solid-state relays and AC solid-state relays. Bipolar devices or power field-effect transistors can be used for DC output, while two thyristors or one bidirectional thyristor are usually used for AC output. AC solid-state relays can be further divided into single-phase AC solid-state relays and three-phase AC solid-state relays. AC solid-state relays can be classified into random-turn-on AC solid-state relays and zero-crossing AC solid-state relays, based on the timing of conduction and turn-off.

A bipolar junction transistor is made by fabricating two closely spaced PN junctions on a semiconductor substrate. These two PN junctions divide the entire semiconductor into three parts: the middle part is the base region, and the two sides are the emitter region and the collector region. There are two arrangement types: PNP and NPN. Corresponding electrodes are led out from the three regions, namely the base b, emitter e, and collector c. The PN junction between the emitter region and the base region is called the emitter junction, and the PN junction between the collector region and the base region is called the collector junction. The base region is very thin, while the emitter region is thicker with a high impurity concentration. In PNP type transistors, the emitter region "emits" holes, whose movement direction is consistent with the current direction, so the emitter arrow points inward; in NPN type transistors, the emitter region "emits" free electrons, whose movement direction is opposite to the current direction, so the emitter arrow points outward. The direction of the emitter arrow is also the conduction direction of the PN junction under forward voltage. Both silicon and germanium bipolar transistors have PNP and NPN types. Transistor package forms and pin identification: Common transistor package forms include metal packages and plastic packages. The pin arrangement follows certain rules. When placed in a bottom-view position, the three pins form the vertices of an isosceles triangle. From left to right, they are e, b, c. For small and medium-power plastic transistors, when the flat side faces you and the three pins point downward, from left to right they are e, b, c.
