I really hope they work, it could be better if they were in antistatic bags, i got one from ebay that was fried from ESD probably cuse it did not work. But anyway i am happy with my buy. Also price is good fo4 three models.
Ideal for motion detection.
Fast delivery. The sensors are in good condition. It is very good value for money. Thank you Bang good Regards, I.Patev

This model is a nice low cost radar module to experiment with doppler X band RF signals.

need complicated electronic circuit
This product requires loads of work to be useful. It lacks a useful output level, it's hardly well developed at all.
