I need to connect to my Arduino nano two PIR motion sensors.
But I can’t connect them to separate pins because I use previous wire setup with only 2 wires.
So, my idea is to connect the parallely with same signal wire, same ground wire and independent VCCs.
I have tried to do that like on the sketch but it works only if two sensor are triggered at the same time like AND function. When one sensor is triggered I measure 1,8V between GROUND and SIGNAL wires. If two sensor are triggered there is 3,5V and then it works.
Anyone have a solution how to connect them with two wires in order to run my action if any of them is triggered or two of them at the same time (like OR)?
I can not find any similar solution in Google
