Existence sensor

Abstract

The invention provides an existence sensor, and belongs to the field of Internet of Things automation. According to the sensor, the sensing range is increased through the lens, and continuous detection of moving and static people and objects is achieved through the light sensor (such as a common imaging sensor) behind the lens. At present, the recognition rate of an imaging sensor to people is very high through firmware, accurate recognition can be achieved no matter whether the imaging sensor moves or is static, color changes and light changes can be detected at the same time, and multiple functions are integrated at a low cost. And automatic work of various environments requiring people to be powered on and powered off when people walk, active prevention and control of dangerous occasions such as fire disasters and the like can be realized. The device is used for smart home, can more intelligently simplify various sensors, and can realize unmanned operation in dangerous occasions.

Description

technical field [0001] The novel device of the present invention uses a lens plus a sensor as a signal acquisition device, and relates to automatic execution tasks in various industries. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of science and technology, people's requirements for equipment automation are also getting higher and higher. At present, the sensor has a single function, a narrow sensing range, and cannot continuously monitor the target state after one response, which is prone to false positives. data. For example, the mobile sensor of the Internet of Things can sense when people are moving, but not when they are still. The vibration sensor can sense when there is vibration, but it cannot sense when there is no vibration. The same is true for light control and sound control. At present, there is no perfect all-round Sensor, and the sensing range of this type of sensor is only limited to th...
