It's for the engine temp.

The max 120ºC of the DS18B20 is not enough.

I need to be able to read safely up to 140ºC.

I know you will say that the engine cannot reach that temperature unless it's toast, but the real thing is that with 30% nitro they can have peeks of 130ºC/135ºC. Not too good for the engine, it's true, but i need to measure it's peeks to know how the engine is running in mid air
