Is there a specific node for SR602 PIR detector in XOD IDE or should I go ahead and treat the incoming digital signal just like any other HIGH/LOW input?
I have read that this particular sensor required some auxiliary circuit to prevent false positives which it is known for.
Thanks.
If it has a tendency to give quick blips as false-positives, you can look at the debounce node to filter the output for you.
Hi,
I have two sensors at hand.
MH-SR501 and MH-SR602.
I could not get any reading out of them into Arduino Nano V3 with XOD.
I have tried digital-read and binary-sensor nodes.
I keep reading False on the Debugger screen’s Watch node?
I have managed to get the MH-SR501 working by the use of an external PS as it looks like nano’s juice was not enough for the modules.
However,
MH-SR602 is behaving strange still. It seems that it has a fixed timer value of 3.5 seconds. How can I control this value? I have read online that timer value was configurable via the Arduino MC.
But how?
There seem to be many mounting options for these parts. Some include POTs for variable resistors, others require replacing surface mount resistors to change timer and other values. I didn’t notice any that allowed remote setting of timer. The output of SR602 piece that I found is 3.3v. That could be a problem detecting high value depending on Arduino model you are using.
