Using an IoT approach for the fHelper can helps to evaluate the measurements done more easily, using the MQTT protocol.We need a server capable to receive the measurements from the fHelper sensor (client) and eventually work on the received data.
And of course we need a client/sensor capable to send the humidity level to the server.
See the article about the MQTT/Node-Red server about the preparation of an IoT server on a Raspberry Pi.
This article is about how to quick set up an IoT client for fHelper in order to run some feasibility tests on the sensor and its response.
Basically the idea is to evaluate if the system is reliable enough for the purpose.
