24GHz mmWave Sensor - Human Static Presence Module Lite

Are you a hobbyist looking for the latest technological advancements to automate your home or office? Look no further than the 24GHz Mm-Wave Sensor Human Static Presence Module Lite! This sophisticated module is perfect for creating the automated environment of your dreams. 

24GHz mmWave Sensor - Human Static Presence Module Lite is an antenna-integrated, high-sensitivity mm-wave radar sensor that is based on the FMCW principle. It is user-friendly by providing visual debugging and configuration tools. It can flexibly adapt to various scenarios as multiple underlying parameters is configurable. With Arduino support, it is an easy-to-use and cost-effective choice for various human presence-detecting applications.

This radar assembles multiple functions in one device which are customizable with your own definitions.

It can detect human presence and absence, the motion and the direction of motion, object speed, and detected distance. Meanwhile, it provides the open custom function by offering adjustable underlying parameters for you to adjust detected range, sensing sensitivity, trigger threshold, valid time for states changing, and installation environment.

There is also an underlying open function provided and the parameters from it are the statics noise of the environment, the detection range of presence, motion noise of the environment, the detection range of object moving, and the detection speed of an object moving. That is, you can utilize its performance to build your own object movement detection radars, to meet the different needs in various scenarios.


What are FMCW's advantages?

Based on the principle of millimeter wave radar and FMCW ranging technology, the radar only needs to calculate the high-frequency continuous waves emitted to and received from the objects, without any privacy risks. Designed with a low power output, the radar maintains a health-friendly working status when it is observed. Thanks to its high immunity against interferences, the output data is less vulnerable to environmental influences like temperature, humidity, noise, airflow, dust, light, etc.

Most Amazing Part: Visual debugging and configuration tools

The hardware design of it is scalable and supports secondary development based on related upper computer software(Windows) and Arduino. It can be even amazed that the radar can be upgraded by OTA(over-the-air) programming method as the board can be upgraded locally. Combined with its multiple customizable functions, this radar is an ideal motion-sensing solution in times of devices getting smarter. It presents a range of functional configurations that can be developed for realizing various application requirements.

Upper Computer Software

There is an upper computer software related to this radar, published for real-time acquisition and visualization of radar data, that displays sensing parameters through real-time waveform images which makes data monitoring more intuitive and clear. Meanwhile, it offers a series of actionable items generated by serial command protocols. Both of them help to increase development efficiency.
