With this Phidget, you can connect up to four thermocouples to a single VINT port, making it ideal for temperature testing and comparison (See the "Compatible Products" tab for a list of VINT Hubs). You can use a J, K, E or T type thermocouple; set the appropriate type in software and it will convert sensor data into degrees Celsius automatically. If you have other thermocouple types, you can open the channel in VoltageInput mode and convert to temperature manually according to your thermocouple's datasheet.



Long Wires

One of the major advantages of using a thermocouple is the capability of using long wires. Thermocouples have been known to work with segments as long as 100m, while USB and other sensors suffer from voltage drops after 5 or 10m. You can find thermocouple extension wire on the Compatible Products tab. Please note that the longer you make your thermocouple wires, the more likely it is that you'll experience noise and interference. For more information, see our document on Addressing Electromagnetic Interference.

Getting Started

Welcome to the TMP1101 user guide! In order to get started, make sure you have the following hardware on hand:


Next, you will need to connect the pieces:

TMP1101 Functional.jpeg
  1. Connect the thermocouple to one of the inputs on the TMP1101. The datasheet or product page for the thermocouple should tell you which wire is positive and which is negative.
  2. Connect the TMP1101 to the VINT Hub using the Phidget cable.
  3. Connect the VINT Hub to your computer with a USB cable.


Now that you have everything together, let's start using the TMP1101!

Using the TMP1101

Phidget Control Panel

In order to demonstrate the functionality of the TMP1101, the Phidget Control Panel running on a Windows machine will be used.


The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:


Linux users can follow the getting started with Linux guide and continue reading here for more information about the TMP1101.

First Look

After plugging the TMP1101 into your computer and opening the Phidget Control Panel, you will see something like this:

TMP1101 Panel.jpg


The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.


The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Temperature Sensor (Thermocouple)

Double-click on the Temperature Sensor object, labelled Thermocouple Input, in order to run the example:

TMP1101 TemperatureSensorThermocouple Example.jpg


General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
  • Select your thermocouple type from the Thermocouple Type drop-down menu.
  • The measured temperature will be updated next to the Temperature label. Touch the thermocouple wire with your hands to see the temperature increase. If the temperature decreases when it should be increasing, you may have the wires plugged in incorrectly.


Temperature Sensor (IC)

Double-click on the Temperature Sensor object , labelled Temperature Sensor (IC), in order to run the example:

TMP1101 TemperatureSensorIC Example.jpg


General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
  • The measured temperature can be seen next to the Temperature label. Cover the board with your hands to see the temperature quickly rise.


Voltage Input

Double-click on the Voltage Input object in order to run the example:

TMP1101 VoltageInput Example.jpg


General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.

Technical Details

Cold Junction Compensation and Self-heating

Thermocouples consist of two junctions, one where the thermocouple meets the Phidget and one where the two wires are welded together at the sensing end of the device. In simplified terms, a thermocouple works by detecting the temperature difference between these two junctions. As such, in order to measure the temperature at the sensing end we need to know the temperature where the thermocouple connects to the Phidget. To do so, there is an ambient temperature sensor on the board.

An important thing to note is that the ambient temperature sensor measures the temperature of the board and the air around it, though not specifically at the junction. Generally you can assume they are nearly the same temperature, however as the electronics heat up by being powered on there can be some small error introduced. This is exacerbated by having the board in an enclosed space where normal airflow is restricted thereby increasing the effect of self-heating. As a result we recommend that the board be left in as open and well ventilated/cooled a place as possible to minimize this error source.

For more information on thermocouples, check out the Thermocouple Primer.

Thermocouple Accessories

Here are some handy accessories for working with thermocouples. Extension wire, adapters, and plugs can be found here.

VINT Hubs

This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:

Image Part Number Price Number of VINT Ports
HUB0000_0 $30.00 6
SBC3003_0 $120.00 6

Phidget Cables

Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

Product Physical Properties
Image Part Number Price Cable Length
3002_0 $2.00 600 mm
3003_0 $1.50 100 mm
3004_0 $3.00 3.5 m
3034_0 $1.50 150 mm
3038_0 $2.25 1.2 m
3039_0 $2.75 1.8 m

Thermocouples

You can connect up to four J,K,E or T type thermocouples to this Phidget. See the product page or data sheet for the thermocouple to determine which end plugs into the positive terminal on the Phidget. If you're not sure which end is which, it won't harm anything to try both configurations to determine which one is right. If the thermocouple is hooked up backward, you'll get erratic readings and the temperature will decrease when it should be increasing.
