[Andreas Spiess] chosen up a few low-cost radar sensors. He decided to compare the gadgets as well as test them and–lucky for us–he collected his results in a video you can see below.
The concerns he wished to response were:
Are they 3.3 V-compatible?
How much present do they draw?
How long to they show a detection?
How far away can they find the movement of a typical adult?
What is the angle of detection?
Can they see with specific materials?
Can the gadgets coexist with other gadgets in the exact same area? What about WiFi networks?
Good listing of questions, as well as if you want to understand the answers, you should watch the video.
The gadgets he examines are the RCWL-0512, HW-MS03, WB3-12, XYC-WB-D1, as well as the HFS-DC06. The RCWL module is the least expensive, as well as we discovered a number of locations selling them for anywhere from fifty cents to a dollar each. the most costly module–the HFS-DC06–is about $5.
If you are thinking about these, this video will save you a great deal of experimentation time. The boards are all somewhat similar, however [Andreas] covers the differences between them early in the video.
We’ve seen affordable radar detectors before, however not this cheap. We’d like to revisit a few of the other radar jobs we’ve seen in the past as well as see if they might utilize these extremely affordable devices.
