Temperature Sensor
An open-source, Arduino-based temperature sensor for the VasoTracker myograph system (or for any other application)
Building the Temperature Sensor
Once you have all of the components, you're going to need to do a little bit of soldering...
- Build the proto shield. For AdaFruit, solder on the headers and snap off the removable part of the PCB.
- Build the temperature sensor circuit on the proto shield, as shown above. The thermistor should be connected to the shield using a screw terminal.
- Stack the proto shield on top of the Arduino.
- Stack the LCD Shield on top of the proto shield
- Connect the power supply to the Arduino. To supply sufficient power, we recommend a 12V power supply. Only use the USB cable for data transmission.
- Optionally, build an enclosure. You can build one using Lego®, or you can 3D print one of the enclosures below.
Notes:
- If you want to power the temperature monitor and pressure monitor using a single power supply then you should remove the Vin and GND pins from the proto shield. You can daisy chain these Arduino pins. Hint…. this is only useful if you want to use the dual enclosure.

Sketchup, Fusion 360, step, and stl files for the VasoTracker temperature monitor enclosure. Designs most generously contributed by Nathan Tykocki (check out the Tykocki lab).
Some proto shields and LCD shields may not quite fit. If this is the case, we have provided various file formats that you can modify. Please do not ask us to!
