I’m wanting to remotely monitor level in a tank with pressure sensor using MQTT. I have PLC setup with sensor (which I am familiar with) which can act as a client. However I’m a newbie to MQTT and still getting my head around having broker etc. I have heard that Rasberry Pi running Mosquitto is a pretty good option… in which case I’d also like to have a small screen/display to give show the tank level. Can anyone advise what level of RP I’d need for this?
I understand that I could probably do away with the plc and use RP for measurement as well… but that will probably be down the track as I get more familiar with RP and Python etc.
