In the first example in the article Iglesias says she learned about the sensors in her own school when an admin came to the restroom after it was triggered. Despite it being triggered by actual vaping, she notes that the admin "ultimately let all the students go" which seems to indicate that, at that school, it wasn't being used blindly to convict students.
