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!
