Sensor Shield Stuff

 

I like the Sensor Shield a lot. It's really easy for quick prototyping but does require a good supply of female to female jumper cables. Here's one quick setup that I put together:

 

 

The Hardware has:

 

 

The TMP36 Temperature Sensor is a homebrew card with just three connections:

 

 

A few points to consider about jumper cables may help make this easier:

 

  • 4-pin to 4-pin female to female connectors are nice, but the Adafruit style LCD I2C backpack isn't pinned out the same as the Sensor Shield. I used a pair of 2-pin to 2-pin female connectors. The only painful part is that the color code isn't identical since one end has to have one of the pairs (SDA-SCK) swapped.
  • If you have a LCD with a YwRobot style I2C adapter you can use a straight 4-pin to 4-pin female to female cable.
  • 3-pin Female to 1-pin female (splitter) cables are really optimal for most of the pins on this shield.. 
    • I wired my TMP36 connector to match the TO-92 (transistor package style) and not the cable. That means I can't connect it with a 3-pin to 3-pin female-to-female connector. That's where the 3:1 splitter comes in handy. I marked the card connections with GVS (Ground Voltage Sensor) just like the sensor shield so I don't have to trace the lines again.
    • The MMA7361 has connections which are best attached with the 3:1 splitter cables. This method leaves a few extra power/ground connections which were nice for pulling up/down the control lines.
