From your question, I got something that you installed the Sensors-unity app from Ubuntu Store but it won't launch and so you need to information about Sensors-Unity Application!
After installing the application, you can find the information about the app using the following command:
$ sudo snap info sensors-unity
It will ask you the system password, provide the password and execute the command.
The complete information about the application will display in the Terminal as shown in the below example.

Allows monitoring the output of the `sensors` command graphically.
**Note:** for sensors-unity to work you have to manually give it the
hardware-observe permission in the software center or using the CLI as:
snap connect sensors-unity:hardware-observe :hardware-observe
