In my constant study and exploration and attempt to become wiser, not only in Flowcode also all the componet in Flowcode, I found the component ebm016 which
is a SHT21. Compared with a DHT22 they have the approx. the same accuracity. A SHT21 use I2C and DHT22 is onewire.
Anyway, I have a look at the example in the helpmenu, very interesting. I went to Ebay and bougth a couple of these:

They are preparered to 5v and pull up, ready to connect to a Pic.
They arrived today and they have to immediately to be tested. Connected to my pic16f876a (was in my EB06) picup the program from the helpmenu from this component, change the configuration to a Pic16f876a ect, compile to pic and ooppss

Later I will make a test with this SHT21on an Arduino with FC´ example...
My best recommendations and experience with FC example in helpmenu for SHT21 component. Fast and easy. Thanks to MM.
