Nitrogen-vacancy (NV) centers in diamond carry spin degrees of freedom that enable their use for sensing of weak magnetic fields with high spatial resolution and under ambient conditions. This article reviews measurement technologies and identifies the physical mechanisms that limit the sensitivity with a focus on NV ensembles. Present-day NV sensors are far from theoretical limits imposed by quantum mechanics, and strategies are suggested for improvement of methods and materials.
