Perfect!You don't want to power the yellow (data) wire, only want the pullup resistor at 3.3v which you likely have already. If so, just move the red + wire to +5v.
Yeah the sensors work better at 5v, as long as the pullup is going to 3.3v the Pi 3.3v tolerant pin will be ok.
3 days ago I changed for the second time my power supply and it hasn't failed so far (this time it's s 3 amp power supply). If it does fail again I'll try to change the voltage, thanks!!!!
I'll keep you posted haha
