Abstract
The invention discloses a sensing device with an adaptive frequency modulation mechanism and a method thereof. The sensing device comprises a microwave sensing module, a wireless communication module and a processing module. The microwave sensing module has a first register value. The wireless communication module broadcasts a first signal including a first register value. The wireless communication module receives, by an adjacent sensing device, a second signal including a second register value of the adjacent sensing device. The processing module compares the signal strength of the second signal with a preset strength threshold value, and performs register value comparison when the signal strength of the second signal is greater than or equal to the preset strength threshold value.
