hello, its a nice video, but i have a question ? do you use hivemq websocket client for MQTT broker?

Thank you. I have used 1883 port in this video which is a Tcp port. You can also use websocket port 8884 if your application demands it

Where is the broker running ? Are the MQTT Broker and Wifi Connections WOKWI virtual connections ?

[@IoTFrontier]

I have used hivemq public broker as shown in the diagram in the video. The wifi used in Wokwi is the virtual connection.

Sir please help me out with this question, When I enter any line, I receive nan data ? and I can't deploy it myself, because then the data returned is nan

[@IoTFrontier]

There could be multiple reasons. Few of them are here 1. Sensor might not be working 2. Sensors connections might be loose Check it properly or try to use another sensor if available This is applicable if you are using the real sensor instead of simulator
