This product is a 24GHz dual-channel millimeter wave radar sensor. The module adopts a planar microstrip antenna structure and is very compact in appearance; it is easy to integrate into various circuits Used to detect the distance between moving targets and stationary targets and the sensor; human body detection distance range 0. - 20M); accuracy 0.1M. Moving vehicle detector detection distance 50M (customers can adjust the distance according to needs, accuracy 1M have high sensitivity and are widely used in blind spot monitoring, straight driving, electric bicycles, electronic security, automatic control, sports, industrial machinery and other fields If the module is designed with a shell, the best distance between the radar antenna and the shell is 6mm, and the shell thickness is about 2-3mm. The shell material cannot be made of metal or metal-plated paint. It is recommended to use PC, plastic, steel, etc This module only detects relatively moving targets within the detection area, and does not detect completely stationary targets. The output result is information such as the distance to the nearest target in relative motion within the detection area 24GHz (ISM standard frequency band) based on radar working principle Mobile human detector detection distance:0.3-20M Moving vehicle detector detection distance:50M Power input range:5-12V Transmission frequency:24.000-24.250GHz Transmit power:5dBm Antenna style:horizontal angle 41/vertical angle 120 Operating current:79mA (5V) Working voltage:DC 5V-12V Working temperature:-40-85 Data interface:TTL serial port Data format:115200, 8, n, 1 Response time: equal 60ms Level output:reserved, not used Detection blind zone:30cm Detection accuracy:10cm Colour:GreenMaterial:PCB Package Contents: 1 * Speed Radar Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
