hi Catalin,

No, the charger should not get hot, neither warm actually. I suspect there is something wrong with the charger you received. As a quick test, please use the SMOGGIE-CO2 charger to see if the problem goes away.

Then I can either send you a replacement charger, or simply use any of the standard USB ones you may have lying around from old phones or tablets. SMOGGIE needs very little to run, so even a 5V 250mA charger would work (most are 5V 1A).

hi Adam,

You can send it back via http://www.uradmonitor.com/rma

Before you do that, try to see if you can get the USB commands working. I am especially interested in seeing the “default” command working on your unit, to restore it to factory default. See: https://www.uradmonitor.com/wordpress/wp-content/uploads/2020/08/uRADMonitor_USB_commands_comp.pdf

Sorry for that. Yes, this is under developement and hope to see it soon. You’ll be able to setup notifications from http://www.uradmonitor.com/dashboard in your account, including when the unit detects some predefined values, etc.

Yup, totally agree! Also a community flagging option (vote based, etc).

Yes, but only with a firmware update . This feature is implemented in code, but not activated on production firmware.

hello Ken,

I am glad you fixed it successfully.

The PM sensor must not be mounted on top of the PCB,

instead it must go through the PCB in the designated area. Basically it fills the entire aluminium enclosure height, going through the PCB.

Here’s a picture:

hi Catalin, seems something went wrong when provisioning your unit with the custom firmware . I will get back to you with the correct firmware on email. It’s very easy to program it, here are 2 tutorials:
