LD2451 is a 24G radar module with integrated 1T2R (one way transmit, two ways receive) RF transceiver channel, which can achieve accurate measurement of near, medium and long range multi-target distance, speed and orientation in the detection area. Mainly used in high-speed intersections, non-motorised lanes, motorised lanes and intelligent driving scenarios, to achieve the state of the rear vehicle detection.<br><br>Frequency: 24G-24.25GHz Sweep bandwidth: 250MHz Modulation mode: FMCW Power Requirement: 5V(Typ.) / power supply capacity Greater than 300mA Detection angle: ±20 Detection distance: Maximum sensing distance 100m Ambient Temperature: -40℃-+85℃ Data format: serial port ASCII output, GPIO level output Colour:Photo Color Material:ABS<br><br>Package Contents: 1x Vehicle distance and speed sensor<br><br>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.
