You say that you ship from Switzerland. So I payed for that. But I received the shipping information that my package will be received from China (Shenzhen). It usually takes much longer for packages to arrive from China. Strictly speaking, it would not be part of the sales contract. I need the sensor, so I'll have to wait. That is annoying. The shipping costs are therefore not conclusive and transparent for me. Especially since half of the order was almost the shipping costs.

Hello! We're very sorry you got that impression... in the HB100 product description is mentioned " Shipping will be done from Switzerland or Shenzhen depending on current stock and customer location."
Hi... I recently purchased this module for detection moving people in the room. External view of module is very good, and from VOUT output i have useful signal (>2.5V wheh i moved) But I have a questions. 1) If I have not moving in room with your sensor, what sighal i have in FOUT ? I think 0, but i have not null frequency. 2) And you in your speed measure's sample for arduino you connect FOUT to digital input of arduino. But output FOUT of sensor is analog signal, isn't it ? Why he is connected to digital input ?

Hello, 1) You'll see noise on the FOUT output, which is why it is important to make sure that VOUT is relatively high to take into account FOUT. 2) FOUT is digital, VOUT is analog. Would you modify your text content with a review? Thanks!
