24GHz Radar Speed Sensor Support RS485/TTL, Measurement Range 1-240km/h & 120m Long Distance Detection, ±1KM/H High Accuracy

Product Intro

The TR21M speed radar is a millimeter-wave radar module integrating a microstrip antenna, RF circuit and signal processing circuit, which directly outputs the speed information of the target. It is widely applied to speed monitoring on various types of roads such as expressways, urban trunk roads, county and city grade roads, and urban and rural arterial roads.
