Now that I have established my standard for sensor connections I will need build the hub to hook up the sensors. So I build a 2 connector RJ45 jack hub to test the sensors that I build. This hub will allow me to test different sensor configurations and arduino sketches for test sensors as I develop them.
Here is what it looks like.
I have marked the terminals on both ends so there can be no confusion as to what connections are being used. Make sure you have test all the connections with your multimeter. That way you know for sure everything is working before you start testing situations with sensors.
