Formula Rules

[isva]

Hello,

I would like to make a formula: My sensor post 8 cm HC-sr-04. I would like to calculate a volume. 8*(100*100).

Someone has an idea?

Thank you for the coperation

Best regards Vinc

In order to compile, you have to download the source files, modify them and then compile them in the ArduinoIDE. There is a tutorial in the wiki

There is however a simpler solution to your problem; rules :-

1. Activate rules under the advanced tab
2. Create a dummy device with value name Volume (for example as task 2)
3. Under rules tab enter the following code

Code: Select all

On US#distance do 		//whenever there is a Ultrasonic distance measurement do:
Taskvalueset 2,1,[US#distance]*100*100		// use  the value obtained by ultrasoundsensor, do your calculation and write it to the dummy
Endon

That should be all
