The JF04 mini presence sensor uses 24GHz millimeter wave radar and FMCW radar detection and algorithm to detect dynamic situations by measuring the frequency difference between the transmitted signal and the reflected signal. Being able to identify and determine the dynamic changes in the chest and abdomen during breathing, thereby achieving accurate human presence detection.
The JF05 mini high-altitude microsensor uses a high ceiling radar chip to transmit and receive high-frequency radar signals, which are processed by algorithms. Even at heights of 2 to 12 meters, it can sensitively detect small movements and motion states of the human body. This includes but is not limited to nodding, shaking, waving, raising hands, small body movements, using smartphones, flipping through books, as well as movement states such as walking, brisk walking, jumping, spinning, and running.
Functional Overview
Using 24GHz millimeter wave radar and FMCW radar detection and algorithm, dynamic situations are detected by measuring the frequency difference between the transmitted signal and the reflected signal.
Selection Suggestions
is widely applicable to scenarios that require human detection, such as homes, office buildings, hotels, banks, hospitals, schools, airports, museums, laboratories, factories, etc. It is also suitable for professionals such as weak current integrators and smart home solution engineers.
