Adafruit PIR Motion Sensor

Q: I am trying to get these to drive the coil on these relays, but its not a strong enough signal to trip them. What am I doing wrong?

the 3.3s volt is a "Signal" voltage. It is not meant to drive a relay. You need more power to do that. Use a different kind of relay or build a driver circuit. Then you can use the signal "3.3v", to turn the relay on and off.

Q: Does it come with the wire it shows in the picture? Some reviews make it seem like it may not.

Mine came with the wires as shown.

Q: what is the maximum distance from the sensor to the pi?

I don't know about maximum, but I used it with 8- to 12-inch leads and it worked fine.

Q: Where is the sensor on this board and how big is it?

The sensor is on the opposite side of where the wires connect to it. Check the pictures out in this link on adafruit's actual site its the same one they just have more pictures of it: https://www.adafruit.com/products/189?gclid=CMSg0JyG9s4CFUFkhgodYkEFbA
