**4. Discussion**

Based on the aforementioned measurement results of the low-cost sensor controller platform, the following lessons were learned and conclusions drawn:


Furthermore, in order to avoid confusion, it is useful to apply filtering methods with a relatively slow sampling rate so as not to result in rapid fluctuations that are not related with muscle contractions. Future work includes the deployment of multiple IoT SNs and incorporation of the MQTT mechanism between Gateway and those Nodes. An IoT platform with database could be also used within the Gateway to perform further analysis of the received sensor values and handle all critical alerts on premises.
