NTC thermal resistance and temperature measurement principle.Human Body Infrared Temperature Sensor

　　NTC thermistor refers to the phenomenon and material of the aid resistance with a decrease in the index relationship with the temperature rising resistor and the negative temperature coefficient. These materials are generally two or more of high -purity metal oxides such as manganese (MN), cobalt (CO), nickel (Ni), aluminum (AL), zinc (Zn) as the main materials. The nanowe material synthesized by thermal method, the ball mill is fully mixed, and the static pressure molding, high temperature sintering, semiconductor slices, sliced slices, glass sealing or epoxy packaging processes, etc. Electronic ceramic materials, these metal oxide materials are semiconductor, because the conductivity is completely similar to 锗, silicon and other semiconductor materials. It has the characteristics of the corresponding changes with the change of the resistance.

　　In order to ensure the normal operation of power semiconductor components, logic elements, microcontrollers and processors, it must be tried to avoid overheating. NTC thermistor can be directly placed near the microcontroller and other hotspots on the microcontroller and circuit board. Since the welding joint and the circuit board can form a good thermal contact, and the spontaneous heating of the component is slightly slightly slightly slightly slight, the new thermistor can monitor high -precision temperature for semiconductor sensitive components.

　　Advanced charging technology not only requires the battery to have as much as possible as possible, but also to ensure that the charging current at the highest allowed temperature is lower than the maximum charging current at the battery. When the charging current causes the battery to reach the temperature limit, the rechargeable battery must reduce the current accurately and avoid damage. The more accurate and faster the battery temperature changes, the more accurate and faster the charging current adjustment. This technology can ensure that the battery is charged in the shortest time, and the battery can be avoided.
