<p>How did you deal with it in the context diagram? As an entity that sends data to the system or as part of the system?</p>

Hi all<br>
<br>
Can a machine / devise / sensor be an entity in a data flow diagram?<br>
<br>
I want to model an Arduino home project I have been working on for my students. Three temperature sensors inside a solar heater will determine the fan speed of an output fan blowing warm air into my house during winter. The user will be able to view temperature,
fan speed, watts generated, minimum/maximum temperatures and be able to change fan trip levels and CMF ratings.
<br>
<div><br>
It would be easy if I could treat the Arduino device and sensors as being an entity that has inputs and the code to be viewed as the process. Level One and Two drawings would break up the sub-processes. Not sure if this technically correct?<br>
