Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] refer to figure 1 -2, the human body sensor is provided with a power supply circuit 2 providing a suitable DC power supply, a microprocessor 1 for centralized control, a human body infrared sensor 3 and a microwave Doppler sensor 4 connected to the microprocessor 1 .
[0016] The human body infrared sensor 3 detects the infrared radiation signal emitted by the human body, and a human body infrared temperature sensor can be used. This sensor adopts infrared thermal imaging technology and is designed into a pixel matrix structure, and each pixel corresponds to a block of the detection area. The output data of each pixel represents the average temperature of the area, so static and dynamic human bodies can be detected.
[0017] The human body infrared sensor 3 can also be an infrared pyroelectric sensor. This type of sensor works by detecting infrared radiation f...
