Embodiment Construction

[0022] In the following, several embodiments of the present invention will be disclosed with accompanying drawings and text. For clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In addition, for the sake of simplification of the drawings, some known structures and elements will be drawn in a simple schematic manner in the drawings.

[0023] The present invention is an automatic calibration method for sensors, which is preferably suitable for human body movement sensors, such as Pyroelectric Infrared Radiation Detector (PIR), but is not limited to this. In other embodiments, it can also be applied to other similar sensors, as long as it uses object motion detection to further control the device, it can be incorporated into the present invention.

[0024] See Figure 1A and Figure 1B , Is a kind of sensor 1. In this embodi...

Abstract

The invention discloses a sensor and an automatic correction method for the sensor. The automatic correction method comprises the steps of: (A1) setting a default trigger value; (A2) sampling a signaland accumulating a signal value to perform signal judgment; (A3) determining whether a trigger condition is met or not; (A4) if so, recording the accumulated signal value meeting the trigger condition, and if not, returning to the step (A2); and (A5) analyzing and updating the default trigger value.

Description

Technical field [0001] The present invention relates to a sensor and an automatic calibration method of the sensor, in particular, a human body movement sensor and an automatic calibration method of the sensor. Background technique [0002] In recent years, due to the rise of environmental awareness of energy saving and carbon reduction, automatic control of the operation of equipment in a specific area, such as automatic lighting, access control switches, etc., in accordance with the current environmental conditions or specific conditions of homes or public spaces, has become an important development trend of smart energy saving . [0003] Generally speaking, the aforementioned devices have built-in or connected object motion sensors, and various settings such as brightness, sensing distance, time and other parameters must be manually adjusted before installation. However, not all users can clearly understand how to set. Furthermore, even after manual adjustment, it may not full...
