The sensor laser pointer is an important hardware for the device to feel the external environment. Determines the ability of the equipment to interact with the external environment. It is the hardware foundation of equipment intelligence. Especially in many smart devices. The sensor determines the core capability of the device. A typical sensor is composed of sensitive components, conversion components and conditioning circuits. Sensitive components are used to directly feel the measurement, and conversion components are used to convert into electrical parameters. Sensors have a wide range of uses and types. According to the measurement object, the sensors can be divided into sensors that detect light, radiation, acoustic signals, magnetic signals, force, position information, temperature, humidity, and solution flow rate. Each sensor that detects the same object has multiple applications and different implementation paths.
At present, the focus of domestic sensor technology development and innovation is on materials. The structure and performance are improved in three aspects: the sensitive material changes from liquid to semi-solid. The direction of solid-state development; the development of the structure in the direction of miniaturization, integration, modularization, and intelligence. The performance is developing in the direction of wide detection range, high detection accuracy, strong anti-interference ability, stable performance and long life. With the development of the Internet of Things technology, new requirements have been put forward for traditional sensing technologies. Products are gradually becoming MEMS technology, wireless data transmission technology, and infrared technology. New material technology, nanotechnology, ceramic technology, thin film technology. The development of optical fiber technology, laser pointer technology, composite sensor technology, and laser pointer integration of multiple disciplines.
