Quantum sensors with solid state electron spins have attracted considerable interest due to their nanoscale spatial resolution. A critical requirement is to suppress the environment noise of the solid state spin sensor. Here we demonstrate a nanoscale thermometer based on silicon carbide (SiC) electron spins. We experimentally demonstrate that the performance of the spin sensor is robust against dephasing due to a self protected machanism. The SiC thermometry may provide a promising platform for sensing in a noisy environment ,e.g. biological system sensing.
