Problems solved by technology

[0002] At present, the common PIR sensor (Pyroelectric Infrared Sensor) on the market is easy to be triggered by mistake when the ambient temperature is high, and it may cause the sensor to malfunction when the wind blows or the leaves fall. When the PIR sensor is used in the lamp, it will cause the lamp to be turned on frequently, which will waste energy and reduce the user experience

Abstract

The invention discloses an intelligent sensor, comprising a driving circuit, a constant current source circuit and an induction circuit, wherein the driving circuit and the constant current source circuit are both electrically connected with the induction circuit; the invention utilizes a thermal element and a constant current source circuit based on operational amplifiers , get the voltage signal reflecting the current temperature, connect this voltage to the sensitivity setting pin SENS of the induction chip, so as to control the sensitivity of the induction chip. After using the above structure, when the ambient temperature rises, the sensitivity of the sensor will be appropriately reduced , so that the false triggering of the sensor can be reduced, the waste of energy can be avoided, and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of sensing devices, in particular to an intelligent sensor. Background technique [0002] At present, the common PIR sensor (Pyroelectric Infrared Sensor) on the market is easy to be triggered by mistake when the ambient temperature is high, and it may cause the sensor to malfunction when the wind blows or the leaves fall. When the PIR sensor is used in a lamp, it will cause the lamp to be turned on frequently, which will waste energy and reduce user experience. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an intelligent sensor, which uses a temperature sensor to detect the ambient temperature, and when the ambient temperature rises, the sensitivity of the sensor will be appropriately reduced, thereby reducing false triggering of the sensor, and further Energy waste can be avoided, and user experience can be improved. [0004] An intellige...
