24GHz Microwave Radar Sensor

Microwave radar sensor can detect distance by transmitting and receiving radio wave. Compared with range&distance sensor of other kinds, the radar sensor can provide much smaller size, lighter weight and wider detection range. Besides, the sensor can keep a steady performance even operated in harsh environments and be able to penetrate most non-metallic materials, dust, smoke and fog etc.. What’s more, it can be used to detect distance of multiple targets.

This is a K-band millimeter wave ranging radar with isolated transmitter antenna and receiver antenna. The principle of radar distance sensor is quite easy to understand: transmit and receive microwaves to measure the distance to the surface of an object. The sensor supports FMCW modulation. All the signal processing units of the radar sensor are integrated inside the product, therefore, users can directly get the distance through Asynchronous Serial Interface. For distance detection of multiple targets or measurement application in special condition, users can change the working mode to get and process distance spectral information.

The microwave radar sensor adopts ASI communication, with 57600bit/s band rate and 3.3V TTL logic level, which can directly communicate with upper computer or other MCU, greatly shortening the developing cycle.
Use it with controllers like Arduino to realize more practical and powerful functions such as, car reverse backup radar system, automatic door opener, UAV, passenger flow detection, collision-preventing device.
