According to the commonly used sensor module, OP (op amp) plus comparator is used as the design spindle of the sensing device. The active structure of the conventional sensor module is as follows: when no one moves, only the background temperature is sensed, when the human body enters When detecting the range, the sensor module senses the difference between the human body temperature and the background temperature, and then outputs a weak analog signal, and then analyzes the analog signal to determine whether there is human movement.

However, when using the conventional sensing module, the following problems and defects are still needed to be improved:

Second, in addition, the analog sensor module is analogous to the power supply noise interference and radio frequency interference, making it impossible to play the role of true sensing.

3. If the operator needs to adjust the sensing device through the switch, the function of the switch adjustment can only be achieved by changing the resistance and capacitance in the sensing device.

4. The conventional sensor module is an analog signal. When the operator adjusts through the switch, it must be turned off and then refreshed (Rest) to refresh the sensor to reload the preset parameters.

The power supply module 40 is provided with a power protection unit 400 having a detection voltage.

Please refer to the third, fourth, fifth and sixth figures, which are schematic diagrams of the first embodiment of the preferred embodiment of the present invention, and it can be clearly seen from the figure that the power supply of the embodiment is The supply module 40 is connected to the circuit substrate 12 as a power supply, and the invention can be connected to an illuminating luminaire 5 (such as LED, cold cathode tube, T5 tube or white woven lamp), an audio host with a speaker or a It is a recordable video storage device for the infrared night vision CCTV camera, and the terminal 300 pins 8PIN, 14PIN and 16PIN set in the input device 30 are respectively described. First, the pin 8PIN and the illuminating lamp are used as instructions to first turn on the power. The warming machine lights up for about 10~30 seconds. If there is no constant temperature animal moving within the sensing range after warming up, the illuminating light 5 is completely dark or shimmer; otherwise, when there is a warm animal moving in the detection range, The illuminating luminaire 5 is in a fully-on state; if the constant temperature animal continues to move in the sensing area, the illuminating state is continuously restarted (the illuminating lamp is fully illuminated); when the thermostat animal leaves the sensing area or stops moving in the sensing range, it will again a predetermined time 5 seconds to 5 minutes (or even longer), after which the illuminating lamp 5 emits a light or full darkness, if the illuminating lamp 5 described above causes the illuminating lamp 5 to emit a gleam after a predetermined time of 5 seconds to 5 minutes, It can be set to detect the warm-up animal movement without sensing within 1 hour to several hours after a predetermined time. The illuminating lamp 5 is completely dark and enters the power-saving sleep mode until the sensing range senses that the warm-blooded animal moves again. Returning to the startup illuminating device 5 for full illumination and when the warm-blooded animal leaves the sensing range or stops the active sensing range, the illuminating luminaire 5 emits a dim light or a full dark before the narration, but the predetermined time is input into the programming mode.

Please refer to the seventh embodiment, which is a schematic diagram of the implementation of the preferred embodiment of the present invention. The terminal pin 14PIN and the function of the illuminating lamp are used as the description. The difference between the pin 14PIN and the pin 8PIN is that the operator can further By switching the switch, the operator can pre-input into the second control unit in the central processing module by predetermined parameters (eg, time adjustable, adjustable illumination, and slightly bright adjustable) to achieve the following characteristics: 1.

Finally, the terminal 300 a of the input device 30 a is taken as an example of a pin 16 PIN. The difference between the foot 16PIN and the 14PIN is that the pin 16PIN retains the functions of predetermined parameters (such as adjustable time, adjustable illumination and adjustable brightness), and can also be connected to a speaker device 5a or an infrared night vision CCTV camera. The recordable audio and video storage device can enable the sensing module 10a to detect the movement of the constant temperature animal after the constant temperature animal moves, and then the connected audio device 5a can produce an acoustic effect or can record the video storage device to start the video operation.
