Hi All,

My current dry box dehumidifier is not working. It's stuck at 65% humidity. Recently, I bought the following from Aliexpress.
1. Peltier thermoelectric module
2. Heatsink
3. Cooling fan
My intention is to replace the old desiccant dehumidifier module in the dry box.

I need some information regarding Arduino microcontroller.
1. Can it go on standby / sleep mode? Only to wake up and take humidity reading when the dry box door is open or at a scheduled time.
2. My setup only need 5V, can Arduino provide the power or I need to provide external power supply.

For my testing on the peltier thermoelectric, I am using USB power supply.

Thanks in advance.
