Certainly not. The IT87xxF chips are made by ITE, while sensors-detect
found a National Semiconductor super-I/O chip on your board.

Your best chance at this point is search for technical documentation
about your netbook and see if they say which super-I/O (or LPC) chip is
used. That being said, I wouldn't hold my breath: most laptops/netbooks
have minimalist super-I/O chips with little to no hardware monitoring
features anyway.
