At present, only one human body induction sensor is generally arranged in an electronic circuit with the human body induction sensor, and circuits related to a sensitivity module and a response time module are single, so that the electronic circuit with the human body induction sensor is difficult to have a good effect in some special fields and occasions.
Referring to fig. 1 to 3, in an embodiment of the present invention, the human body induction lighting circuit includes:
the human body induction sensor 10 is used for collecting infrared energy radiated by a human body and outputting a human body infrared radiation signal, and the human body induction sensor 10 is used for collecting infrared energy radiated by the human body;
the sensitivity setting circuit 40 is used for setting the sensitivity of infrared induction, and when the sensitivity setting circuit 40 is triggered by a user, a corresponding sensitivity setting signal is output;
an LED lamp circuit 30;
the single chip microcomputer 20 is respectively connected with the output end of the human body induction sensor 10, the output end of the sensitivity setting circuit 40 and the controlled end of the LED lamp circuit 30, and the single chip microcomputer 20 is used for controlling the on/off of the LED lamp circuit 30 according to the sensitivity setting signal and the human body infrared radiation signal collected by the human body induction sensor 10.
In this embodiment, the human body sensor 10 can sense the change of the infrared energy radiated by the human body and convert the change into a voltage signal to be output, that is, a human body infrared radiation signal. The human body induction sensor 10 collects infrared energy radiated from a human body within a certain range and outputs a human body infrared radiation signal. When the human body moves within the collection range of the human body induction sensor 10, the infrared energy emitted by the human body is collected by the human body induction sensor 10, and then is converted into a human body infrared radiation signal with certain intensity and then is output to the single chip microcomputer 20. When the human body moves outside the collection range of the human body induction sensor 10, the infrared energy emitted by the human body cannot be collected by the human body induction sensor 10, at the moment, the human body induction sensor 10 cannot generate a human body infrared radiation signal, and the single chip microcomputer 20 cannot receive the signal. Based on this, the single chip microcomputer 20 can determine whether a human body approaches according to the intensity of the received human body infrared radiation signal, and then generate a corresponding control signal to control the working state of the LED lamp circuit 30. For example, the human body sensor 10 outputs a corresponding voltage signal according to the received infrared energy intensity, and the LED lamp circuit 30 is controlled to be turned on/off by the single chip microcomputer 20 according to the received voltage signal, as the output voltage is increased according to the increase of the infrared energy intensity.
Specifically, a voltage value is preset in the single chip microcomputer 20, when a voltage signal received by the single chip microcomputer 20 is greater than the preset voltage value, the LED lamp circuit 30 is controlled to be turned off, and when the voltage signal received by the single chip microcomputer 20 is less than or equal to the preset voltage value, the LED lamp circuit 30 is controlled to be turned on.
The sensitivity signal setting circuit 40 is used for adjusting the response sensitivity of the single chip microcomputer 20 to the human body infrared radiation signal, the higher the sensitivity is, the lower the requirement of the single chip microcomputer 20 on the human body infrared radiation signal intensity is, the lower the sensitivity is, and the higher the requirement of the single chip microcomputer 20 on the human body infrared radiation signal intensity is. Under the condition that the distance between the human body and the human body induction sensor 10 is the same, when the sensitivity is high and the human body is far away from the human body induction sensor 10, the single chip microcomputer 20 can also control the LED output control circuit 30 to work according to the human body infrared radiation signal so as to control the LED lamp to be turned on. On the contrary, when the sensitivity is low and the human body is far away from the human body induction sensor 10, the single chip microcomputer 20 also receives the human body infrared radiation signal, the LED circuit 30 is not controlled to work, and at this time, the LED is kept off.
For example, the human body sensor 10 outputs a corresponding voltage signal according to the received infrared energy intensity, the single chip microcomputer 20 controls the LED lamp circuit 30 to be turned on/off according to the received output voltage, a voltage value is preset in the single chip microcomputer 20, the LED lamp circuit 30 is controlled to be turned off when the voltage signal received by the single chip microcomputer 20 is greater than the preset voltage value, and the LED lamp circuit 30 is controlled to be turned on when the voltage signal received by the single chip microcomputer 20 is less than or equal to the preset voltage value. The preset voltage value of the single chip microcomputer 20 is changed through the sensitivity signal setting circuit 40, when the preset voltage value of the single chip microcomputer 20 is reduced, the human body induction sensor 10 needs infrared energy with lower intensity, the human body induction sensor 10 outputs smaller voltage signals to enable the single chip microcomputer 20 to control the LED lamp circuit 30 to be started, the sensitivity of the corresponding LED lamp circuit 30 to the human body induction sensor 10 is improved, and the induction range of the human body induction sensor 10 is enlarged; when the preset voltage value of the single chip microcomputer 20 is increased, the human body induction sensor 10 needs infrared energy with higher intensity, the human body induction sensor 10 outputs a larger voltage signal to enable the single chip microcomputer 20 to control the LED lamp circuit 30 to be turned on, the sensitivity of the corresponding LED lamp circuit 30 to the human body induction sensor 10 is reduced, and the induction range of the human body induction sensor 10 is reduced.
The LED lamp circuit 30 is controlled by the single chip microcomputer 20, the single chip microcomputer 20 controls the LED lamp circuit 30 to be turned on/off according to human body infrared radiation signals output by the human body induction sensor 10, the sensitivity setting circuit 40 changes the induction sensitivity of the human body infrared radiation signals output by the human body induction sensor 10 by the single chip microcomputer 20, the single chip microcomputer 20 can make correct induction on the intensity of the human body infrared radiation signals under different induction distances, the LED lamp is prevented from being turned on under the condition that no person enters a detection range or turned on and off under the condition that a person enters the detection range, and the application of the human body induction lighting circuit in different scenes is met.

This embodiment can change sensitivity through changing the resistance of first variable resistance R11, and different sensitivities can make singlechip 20 make the right response to human infrared radiation signal's intensity under the induction distance of difference, prevent to export opening signal under the condition that nobody got into detection range or do not export opening signal under the condition that someone got into detection range.
