Recently, A Liang discovered two significant changes in the overseas smart home sector. The first is that major overseas smart home brands are accelerating the deployment of Matter products. The second is that one of the ecosystem platforms, Google, is showing a trend of withdrawing from the smart home hardware layout and focusing more on … Read more
1. Working Principle of Sensors A sensor is a device that converts non-electrical quantities into electrical quantities. The non-electrical quantities sensed typically include pressure, temperature, displacement, concentration, speed, pH, etc. The output is usually an electrical quantity, such as voltage, current, or charge. These output signals are very weak and usually need to be amplified … Read more
The core of solid-state physics is band theory, which categorizes the crystal world into two types: “insulators” and “conductors.” To fill the gap for semiconductor applications at room temperature, the concept of “semiconductors” was added. This knowledge is now taught in secondary schools, indicating that band theory has established its foundation.^_^. Of course, band theory … Read more
[Title] The motion of charged particles in an electric field is a key and challenging topic in electric field problems. This part integrates knowledge of kinematics, Newton’s laws, curved motion, and energy, making it an excellent question to assess students’ comprehensive abilities. The principle of the oscilloscope is a typical problem within this content, and … Read more
1 Sensor Sensors can perceive physical quantities such as force, temperature, light, sound, and chemical components, and can convert them into another physical quantity (usually electrical quantities like current or voltage) according to certain rules, or switch the circuit on and off. By converting non-electrical quantities into electrical quantities, measurement, transmission, processing, and control become … Read more
Sensors Sensors can perceive physical quantities such as force, temperature, light, sound, and chemical components, and can transform them according to certain rules into a physical quantity that is easy to transmit and process (usually electric currents, voltages, etc.) or convert them into the on/off states of a circuit. By converting non-electric quantities into electric … Read more
