Note:
1. The power supply current must be greater than 30mA to drive the module, and the voltage must be stable without large fluctuations, otherwise it will cause continuous triggering (the load light may be continuously triggered by itself or not extinguished)
2. The product should not be installed next to a large-area metal body, and cannot be placed in a completely enclosed metal shell, which will affect the performance of this product or cause it to be unable to be used normally.

In the notes, this product mentions that "the voltage must be stable without large fluctuations". That seems like a bit of an understatement - the voltage must be VERY stable. I tried to power this from my Arduino, which in turn was powered by my computer's USB power (I wanted to do serial monitoring while it was running my test code). This was an epic fail - my computer supply is way too noisy for this board to work properly, it was continuously false triggering. I tried powering it from a bench power supply that also has a USB output on it, and that worked a whole lot better.When powered with stable low-noise power, it senses reasonably reliably. When I say that, I mean that it seems like the range floats a little. The trim pots used to adjust the range are probably at issue here. They probably drift a little, and that drift impacts the sensing range (just guessing). I found that when set to its minimum range, it would detect between about 400cm and 1m, with no noticeable reason for the variation in sensitivity. This may limit its usefulness in precision sensing applications. However, I suspect (and again just guessing, no evidence to back up this assumption) that if you replaced the trim pot with a fixed value resistor set for the desired range it may be more stable. But that is unknown at this point.So, as-is, it is neat to be able to use radar for proximity detection. It is an OK hobby item, fun to fiddle around with and use in test applications. For anything requiring hardened and super reliable electronics, you may need to look elsewhere, or do modifications to improve reliability. And no matter what, you will need a stable power supply.

When I connect this my wifi immediately drops out. It may have been too close to my router since it is in my workshop I haven't tried it in a different location yet.
