I am using a temperature sensor and accompanying devices to prototype a circuit which will be placed in high temperature and humidity conditions. Temperatures up to 40°C and humidity up to 75%. Do I need to make considerations here regarding safety and efficiency or are these conditions not significant enough? I am most worried about humidity as I have found that the temperature I will expose these things to are well within limits of most electronics.
In particular I am wondering, does all wiring need to be insulated and do integrated circuits (such as an Arduino) need to be covered in some way?
As an example, I am using the following temperature sensor which needs to be wired to an Arduino. Does the temperature sensor itself have to be insulated as well ??
