60GHz mmWave radar sensor breathing and heartrate module

Has the red LED been removed from this module? I have received a shipment of these modules but they have no LED and do not work. I suspect they are the falls version. Is there a way of determining the version?

Hello, the new fall radar is the removal of the LED. Did you purchase a breath radar and fall radar and now cannot distinguish between them?

I hope your problem will be taken care of. In case you consider using something cheaper, you can use pulse sensor. I used it. It is quite easy to use. IYou should place your index finger on the sensor.

Purchased heartrate. It appears that they have removed LED from both now. They have also changed the command code which we have discovered!
