I have a Nicla Sense ME, and I found this useful software inside the Nicla firmware GitHub repository:
Under tools there is bhy tool. I am using it to run the web server on my host PC, which connects to the Nicla and plots the output.
(but I had the same result with a basic Arduino sketch to give serial output)
Here's the plot below which is the output shown from ./bhy webserver
I tried some experiments with it:
- putting myself in a small room with the door closed. (no change)
- putting some acetic acid next to the Nicla board
- blowing some butane at the Nicla board
In each case, I could observe no change in the readings.
What could be the problem?
Please check whether your operation is correct.
Download the executable exe package and the corresponding source code package under the release tag;
Execute the following command ./bhy webserver to start the local web server.
You can see that the webserver is started on port 8000, and you can use Google Chrome or Microsoft Edge to access the address: http://localhost:8000/sensor.html
