In mobile technology, the sensor is the primary technology for the input of the measured signal, and it is also a component part of the sensor system. It includes sensitive elements and conversion elements connected to the carrier and the circuit, but the sensor system is a combination of certain information processing capabilities. sensor. The sensor technology applied on the Android platform includes many dazzling sensor technologies such as posture sensor technology, photoelectric sensor technology, magnetic field sensor technology and acceleration sensor technology. The sensor system is very powerful, and many people do not know that the sensor provides users with great convenience.
The sensor is a detection device and a prerequisite device for 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 movement of mobile devices such as mobile phones and computers, and is widely used on mobile devices. This acceleration sensor has now become an integral part of mobile applications. Although the use of acceleration sensor characteristics has become the mainstream trend in the development of mobile applications on the Android platform, there are many problems in the development of applications for degree sensors. For example: large amount of repetitive labor, poor versatility of design schemes and low code reuse rate. In response to these problems of the acceleration sensor, combined with the working principle of the acceleration sensor, a corresponding general design solution to solve these problems is proposed. The purpose of this solution design is to enhance the reusability of the software, shorten the application development cycle, and improve the development of the acceleration sensor. effectiveness.
The basis of the working principle of the photoelectric sensor based on the Android mobile device is the photoelectric effect, which is the change of the measured mobile device is converted into the 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. The photoelectric sensor is a sensor that uses photoelectric elements as detection elements of mobile devices. It includes three parts: light source, photoelectric element and optical path. It has fast detection response, many measurable parameters, simple structure, flexible and diverse forms, non-contact and high precision. Many advantages. It is often used in the fields of mobile equipment detection, smoke and turbidity detection, detection of the size and direction of deviation from the correct position in the processing of belt-shaped materials, and height detection of packaging fillers.
In fact, many mobile phone developers are currently trying to make more use of sensors, not just Android mobile devices, but other mobile devices are indispensable. More micro-smart sensors will be a must-have product in future mobile devices, and more sensors will be used in mobile devices. Sensors will provide smart phones with more complete and powerful entertainment and business functions, making people's lives more convenient.
