Decoding Oregon Scientific temperature sensor

[broderic]

Hello.
I tried a code for receiving and decoding with a PIC the signal of temperature from THN188 Oregon Scientific sensor.
Enclosed is my Positron code and Proteus simulation.
I wonder if someone has some example showing how to decode such sensors with PIC micro-controller.
In internet I found many but with Arduino or so, but none with PIC.
Just to share and compare, to see if mine is adequate or not, if it is too heavy or too unreliable.
For instance I use interrupts but perhaps is not needed...
Thank you.
Regards.
