In mobile technology, the sensor is the primary technology for the input of the measured signal, and is also a component of the sensor system. It includes the carrier and the circuit connected to the sensitive component and the conversion component, but the sensor system is a combination of some information processing capability component. sensor. The sensor technology of the Android platform application has many dazzling sensor technologies such as attitude sensor technology, photoelectric sensor technology, magnetic field sensor technology and acceleration sensor technology. The sensor system is very powerful, and many people still do not know that the sensor provides great convenience for users.

The sensor is a detection device and is a premise device for realizing automatic control and automatic detection of mobile devices. The acceleration sensor of the roid platform is an Android hardware-based sensor, which can effectively track the motion of mobile devices such as mobile phones and computers, and is widely used in mobile devices. This acceleration sensor has become an inseparable part of mobile applications. Although the use of acceleration sensor characteristics has become the mainstream trend of Android platform development mobile applications, there are many problems in the development and application process of the addition degree sensor. For example: large amount of repetitive labor, poor versatility of design schemes, and low code reuse rate. Aiming at these problems in accelerometers, combined with the working principle of accelerometers, a general design scheme for solving these problems is proposed. The purpose of this scheme is to enhance the reusability of software, shorten the development cycle of applications, and improve the development of accelerometers. effectiveness.
The basis of the working principle of the photoelectric sensor based on Android mobile device is the photoelectric effect, which is a change of the measured mobile device into a change of the optical signal, and the converted photoelectric signal is converted into an electrical signal by the photoelectric conversion element of the photoelectric sensor. Photoelectric sensor is a sensor that uses photoelectric elements as a component to detect moving devices. It includes three parts: light source, photoelectric element and optical path. It has fast detection response, many measurable parameters, simple structure, flexible form, non-contact and high precision. Many advantages. It is often used in mobile equipment inspection, smoke turbidity detection, strip material processing, deviation from correct position size and direction detection, and packaging filling height detection.
In fact, there are still many mobile phone developers who are currently trying to use more sensors, not just Android mobile devices, but other mobile devices are indispensable. More micro-intelligent sensors will be a must-have product in future mobile devices, and more will be applied to mobile devices. The sensors will provide smart phones with more sophisticated entertainment business functions and make people's lives more convenient.
