Product Dimenstion
3. Introduction
STF-M2s The microwave ranging sensor is a human body detecting sensor mainly used for automatic control of toilets. Using frequency modulated continuous wave (FMCW) technology, compared with Doppler microwave sensor, it has the advantages of higher ranging accuracy, ability to capture human micro-motion signals and strong adaptability; it can detect peripheral human body relative to toilet in real time. The corresponding detection result signal is sent to the main controller of the toilet. After receiving the signal, the main controller can control the toilet to realize the function of automatically opening or closing the cover or flushing.
