Movement sensing made easy with RFbeams’ K-LD2 Evaluation Kit from Aspen

Aspen Electronics offers the K-LD2 Evaluation Kit from RFbeam Microwave GmbH, a leading supplier of planar radar sensors, K-band measuring equipment and engineering. Typical applications for the K-LD2 are movement detection and speed measurement, plus many other uses.

The K-LD2 Evaluation Kit is a fully operational 24GHz radar movement detector allowing development engineers to quickly evaluate this technology. The K-LD2 24GHz radar module plus a Digital Signal Processing chip provides users with a more complete solution than just the radar module. This will allow those interested in “radar motion sensing” to make better use of the technology as this offering represents a much simpler solution when compared to the prospect of using a radar module and developing your own signal processing algorithms.

The K-LD2 sensor supplied with the kit is a fully digital and low-cost radar movement detector. The sensor features a 2 x 4 patch antenna radar front-end with an asymmetrical beam and a powerful signal processing unit with two digital outputs for signal detection information. The evaluation board visualises the two digital outputs of the K-LD2 using two LED’s. The sensitivity and the hold time are adjustable using analogue inputs with potentiometers. The serial interface features a powerful command set to read-out advanced detection data or to fully customise the detection algorithm. The digital structure makes it very easy to use in any stand-alone or MCU based application where a movement detection or speed measurement is required.

Also included is powerful control panel software where all the parameters can be modified to help drastically reduce development time. The complete module contains everything that is necessary to build a simple, yet reliable movement detector.  Applications are numerous but include door opening; at home automation for lights and air-conditioning, marketing opportunities on advertising boards and POS objects, through to road use for speed measurement or distances between vehicles.
