Temperature & Humidity Monitoring

One of the earliest projects many people build is temperature & humidity measurement, we’ve mentioned this in the past as a simple project.

This project is a more complex version of that, but only in terms of software. What we’re going to build is a simple device which will:

• RS485
• ModBus RTU protocol

Which we demonstrated here.
Obtain the local temperature & humidity value, every minute.
Submit the readings to the message-bus.
The end result will be that I can deploy the same code on a bunch of boards, and each will send their temperature & humidity data to a central queue. From there I can record the values and end up with a useful graphing solution in a hands-free fashion.
