The smell means the electrical wire is either seriously under-rated for the load or there is a serious short somewhere. Ideally, You should have a safety element such as Fuse or MCB etc which will ensure that if current goes beyond the capacity of the wires, then current is tripped off. That way we will have a known failure point. Now, specifically answering your question no. There is no sensor that that detect melting of electrical wires for regular home/industrial applications. The best alternative is VOC and AQI or Smoke sensor which can detect the smell. But again, wires can slowly melt without releasing enough gas for the AQI sensors to detect.
