Durable Ldtr20 Speed Indicator Road Speed Measurement 24ghz Millimeter Wave Radar Sensor Module Traffic Radar Bayonet 1km/h~250km/h Instant 50% Discount [wntobZ6I]

Product Overview:

LDTR20 is a millimeter wave radar module integrated with microstrip antenna, rf circuit and signal processing circuit, which directly outputs target speed information.It can be used for long-distance automobile speed measurement up to 180 meters. It adopts integrated RADIO frequency chip, with high frequency stability and speed measurement accuracy up to 1KM/h.

It is widely used to warn the speed of all kinds of roads, such as expressway, urban trunk line, city and county grade highway, urban and rural trunk road, as well as the warning of road curves and intersection.

Installation instructions:

It should be installed on the left or right side of the road according to the direction of the road vehicles, as shown in the figure below. The height is 1~2m.The recommended Angle between the antenna transmitting surface and the road is less than 10°.

This module only detects the relative moving target in the detection area, and does not detect the completely stationary target.The output result is the speed of the nearest/fastest target in the detection area.
