does anyone have any experience in connecting 2 rcwl-0516 on same arduino uno to increase the detection area ie: connecting in parallel to same output. I've not a lot of experience in programing. Any help would be greatly appreciated,thnx
this particular sensor is only good upto about 5 meters and as i am trying to creat a perimeter alarm across my drive way, I was thinking one sensor each side may do the trick. I was hoping that by using pins 2 and 3 as input and pin 13(conected to siren) as output on the arduino would this work?
What do you mean by "increase the detection area"? How do you arrange the sensors? Do you put one on your house and the other 8 meters away in your backyard? Describe your expectations in more detail.
The main problem I see is the interference the long cable to the second sensor may pick up...
I suggest using either 2 Arduino pins, one for each detector or using a diode in series with the output of each detector.
Only in the case of devices with “open collector” type output can you safely join them together and this RCWL-0156 does not appear to be one of them. See GitHub - jdesbonnet/RCWL-0516: Information about RCWL-0516 microwave proximity switch module (ICStation.com SKU 10630)
It is very unlikely that these sensors will interfere with each other. These operate at around 3GHz and would have to transmit on the same frequency +/- a few kHz to interfere. Due to manufacturing tolerances, this is unlikely to happen.

Try it and let us know.
I thought it can do 8m even, but indeed you'd best just try it out.
It sounds feasible to me.
