Embodiment Construction
[0017] With reference to Fig. 1, one embodiment of the present invention, it is a static detection device 1, comprises a static detection ring 11, a sampling circuit 12, a processing circuit 13, a green light-emitting diode 14, a yellow light-emitting diode 15, a Red LED 16, a speaker 17, a switch (not shown) and a static detection ring jack (not shown). The processing circuit 13 further includes an amplification circuit 131 and a comparison circuit 132 .
[0018] When a user wants to detect the possible static electricity content of his body, he will wear the static detection ring 11, connect the body with the static detection ring 11, and connect the static detection ring 11 to a grounding terminal. Next, turn on the switch to activate the static electricity detection device 1 . On the other hand, the sampling circuit 12 is also connected to the static detection ring 11 for sampling a sample static signal 101 from the user's body through the static detection ring 11 .
