24GHz Doppler Radar Speed Sensor Description
ZLYTR20 velocity measurement radar is a millimeter wave radar module integrating microstrip antenna, RF circuit and signal processing circuit, directly output target speed information. It can be used for long-distance automobile speed measurement of more than 180 meters, using integrated RF chip, high frequency stability, speed measurement accuracy of 1KM/h.
It is widely used in speed warning of highway, urban trunk line, city-county level highway, urban and rural trunk road and other roads, as well as road curve and intersection warning.
