Hi, does any one know the temperature Range the Arduino will operate in.
I am considering using the Arduino in sealed enclosure in an outdoor project, where the temperature have ranged anywhere from [ch8722]40 °C ([ch8722]40 °F) to 30 °C (86 °F).
Thanks!
I think you have to check the temperature range of every (important) component of the Arduino board you're using, in each datasheet, like Atmega IC, Voltage Regulator, Capacitors, crystal, transistor,...
So the higher "low" value and the lower "high" value can be considered as temperature limits.
The ATmega168s are all industrial temperature range devices, -40C to 85C.
As has been pointed out, don't forget the rest of the components.
