I want to ask some questions to you if you don't mind.
I want to use IR sensors that can work between -5(*C) and 85 (*C) but I don't find any sensor like this. All of the product's limit is +70(*C). This sensor should sense 3cm to 30cm sensitively. I will use it in an oven, consequently, the heater area it can work, the better for me.
Please reply my request.
