The TDC1000-TDC7200EVMTDC1000-TDC7200EVM evaluation module has 4 main parts The TDC1000 analog front-end and a pre-programmed MSP430 microcontroller on the board, a 1MHz Piezo Ceramic sensor that plugs into the board and a GUI client for on your PC.
In this blog I'm attaching the Piezo transponder to the "liquid under test" container.

This exercise isn't difficult. There's an excellent step-by-step instructable available on TI's web:
http://www.ti.com/lit/pdf/snaa266
What do you need?
- The sensor from the evaluation kit.
- CYA Latex Glue and activator
- Hot glue gun
- Container for the liquid (I used a plexi box that contained pinterest pins)
- Sandpaper, grid 400
- Hot air gun
- Alcohol (I used isopropanol)
What do you need to do?
All easy steps.
- Sand the part of the container where you want to attach the sensor, and clean that area up with alcohol.
- Dry with hot air gun.
- Apply CYA glue and activator, as specified on your-glue-of-choice's instructions.
My glue, Loctite Super Glue-3, suggested to also sand down the sensor, because the surface is metal.
I had to apply activator first, on both surfaces and wait a minute
Then I had to apply glue on one surface only. I applied it on the sensor.
Then I had to put the sensor on the container and apply light pressure for a minute.
- Clean up any activator residue with alcohol.
- Apply hot glue around the sensor.
- Burry the sensor in hot glue.
- Cool down with hot air gun on minimum temperature setting.
It's a fun activity for a rainy day.The whole exercise doesn't take more than an hour. I spent more time shopping for the ingredients.
