Nice project! I received three SHT11 last week and want to start with it in the next days. So i studied your code and have some constructive critic.

- GOTOīs are not the fine way in "C". I thing a while loop with a small delay would be better.
- Why do you include the TWI lib? The SHT11 isnīt a I2C device!

Overall, nice project. I didnīt know, that proteus has a SHT11 device. I checked it out and find it.

Yes, we didn't use, from the origin i tried to find the sensor then i try to include the other libraries for furture support until got SHT11 then select and no more use and forget to cleaning my code.

The communication is serial. I will try to use the cheaper DHT11 (one-wire protocol) for a similar project, maybe posted here in a couple of weeks.

Interested and hopefully helpful in: DC brushed motor control (mainly R/C - PPM/PWM), analog audio, PIC (mikrobasic PRO). Feel free to ask, and if I can, I will help. But only on forum topics, any started private conversation will continue in a public topic.
