The fan pushes air into the air chamber so you may expect air pressure readings provided via integrated BMP280 pressure sensor to increase a bit. Changes should reflect fan rotation speed (non-linear way, as noted below). text/html 2020-07-20T09:00:00+00:00 Anonymous (anonymous@undisclosed.example.com) https://home.roboticlab.eu/en/iot-open/remotelab/sut/generalpurpose2/m1?rev=1595235600&do=diff M1: Give few words about this scenario.

Here we connect to the existing WiFi network, 2.4GHz. All laboratory nodes can access common access point and require credentials to connect to it (see laboratory description section for the credentials and latest updates).
