Arduino CAN Bus temperature sensor

Arduino with a can transceiver and k type temperature probe. that is all.

Range 0°C to +1024°C

For use with cyclinder head temperature (CHT) Exhaust gas temperatur (EGT) Water/Coolant etc.

Galvanic isolation so sensor can be mounted to vehicle ground without any ground loop issues.
