Hi
Need to build a TMP007 onto of a Huzzah with esp8662- any recommendations as to how to stack these two together?

many thanks

Nothing special.. just connect the VCC, GND, and I2C pins.

Thank you- have that in place on a breadboard - wanting to secure in an enclosure with the temp over the esp8662.
The holes are offset from the boards- any further suggestions?

You'll need to provide some more detail.. which holes, and which boards?

Gnd and v battery on huzzah to tmp007 and Sda and Scl to gpio 4 and 5

Ideally a huzzah with the tmp007 built onboard would be ideal!

That isn't likely to happen any time soon, and it's easy to wire boards together using 30-gauge wire for any connections that don't overlap each other on the footprints. Breadboards are designed for connections made with jumper wires, so I'm unclear on what the technical problem is.

Hi Mike
Thank you for the previous comments-
I am on my 3rd tmp006 and when I solder the components to a header for my setup I get the dreaded no sensor found - albeit the 8266 is available and is posting the errors to the web page.

Are the Tmp006 sensitive to heat whilst soldering and if so how else can i connect these boards together?
In the last photo I am trying to place the temp sensor facedown (pointing through the enclosure) with the 8266 above it and slightly askew due to the space limitations. The sensor is receiving 3 volts and there appears to be no shorting on any of the pins.

The sensor shouldn't be sensitive to the kind of soldering temperatures necessary to connect pin header. It's exposed to a lot more in the reflow oven.

As a sanity check, do you have any other kind of microcontroller you can use to test the sensors?

I have RPis and multiple adafruit arduino devices. currently trying to test the components as they arrive - received 3 new tmp006 - two function okay - one is questionable which i have secured some small croc clips to test without soldering.
Thanks for reply- are you suggesting testing with other arduino modules?

Yes. Try connecting to the TMP007 using an Arduino and see if you have any better luck there.
