"Development of Solar-Powered Food Dehydrator with Temperature Control Simulation"

[Mshakeelzafar]

Hopefully everyone is fine. Currently, I'm developing a food dehydrator incorporating a solar thermal collector for heating. A connected fan will circulate forced air into the food chamber. If the set temperature isn't reached by the thermal collector, a heater will activate to maintain the required temperature. I aim to simulate this process. Additionally, when the thermal collector temperature falls short, the heater will gradually provide extra heat at a rate of 1 centigram per second. The project will include a timer displaying total time, elapsed time, and remaining time, triggering an alarm when the time is up. Graphs will visualize the temperatures of the food chamber, thermal collector, and heater over time. The components controlling the entire process include DSB1820, Arduino, and PID.

I designed it but unfortunately not responding as required.  Please help me in this regard. 

Thank you

Hi

Can you show some coding?

[Mshakeelzafar]

Sir,

For your reference.

Hi

This looks good, but you never control the value of the heater, you only control the colors of the heater.

The best thing to do in my opinion is build subroutines that do art of the calculation and then depending on those values choose what to do.

The big feature of subvi's is that they can be tested independently.

And maybe use an enum to control the case statement, much easier than to try to to get those values in a an integer range.

Thank you, 

Can you please guide me or cab you please design subvi, as I am facing issues to complete it, & timeline is about to end to complete it.

Hi

Creating a subvi is easy. Select the code you want to use in a subvi and in the edit menu select "create subvi from selection" and all wiring is done for you.
