It's nothing to do with infrared, or anything visual, the pits are quite simply thermo-receptors, which can detect really quite minute differences in temperature.
A snakes tongue is sensitive to airborne scent particles, it's purpose is purely olafactory, it cannot detect temperature differences any more than another part of the snakes' body.
