Hi, Would it work to read heartbeat and breathing? Thank you.

Hi, I have two of this similar board but my detection range is only < 5cm on the back side (logo side), and < 3cm on the front (component side). Do you know what could be the issue? Is it both board are faulty? Or I have miss any important setup? Thank you for your attention. Great videos and projects.

Kindly watch the complete video, I have explained how to increase and decrease the range and output ON time.

@@ElectroniClinic Yea I had watch the entire video, at 4:02 you explain to add resistor at R-GN that could control the range. But base on the datasheet, this will only good for reducing the range. My issue here is the detection is only less than 5 cm. So adding any more resistor won't help to increase the range right? Unless I have overlook something, you could enlighten me. 😊

They will be also sensitive to fan movements right?

Ya, if the antenna is facing upwards.
