Thanks DrAzzy.
Then I guess I was looking in the wrong places. Probably I should have started by saying that I already got them when I was experimenting with Arduino, and now I just want to re-use these things with Espruino. I'm always getting them on ebay and they come from Asia.
So I have this PIR motion sensor, relay module, IR obstacle detector and in auction description they said it is 5V so I'm a bit scared to plug them in and experiment :)
