I have a two-way switch for the lights on the staircase and I want to replace them with two-PIR sensors.

I received the sensors yesterday and I discovered that they have only two wires and I am wondering if I will be able to connect the wires to make them work. By having them working I do expect that any of the two sensors to be able to open the lights (close the circuit).

Probably my current configuration is like this: enter image description here

How do I need to do the rewiring?

Easily done:

3-Wire Sensor

  • \$\begingroup\$ When the PIR lets current pass, not only the main lamp but also the additional ones turn on. Is there a solution to this problem? \$\endgroup\$ – aksu May 2 '18 at 17:17
  • \$\begingroup\$ Exactly the same as the switch, so this is expected operation. \$\endgroup\$ – Jack Creasey May 2 '18 at 17:26
  • \$\begingroup\$ Yeah, but say I wanted to turn on the additional lamps with the switch only. Is it a possible circuit or do you think I'd be better off using a relay instead? \$\endgroup\$ – aksu May 3 '18 at 16:38

    \$\begingroup\$ @aksu That is a different question than that posed above. And yes, relays would be the way to achieve it. \$\endgroup\$ – Jack Creasey May 3 '18 at 20:44
