Hi,

i need a PIR1 never used, please PM me.

Thanks. :wave:

Never used?

Well, I actually got on that I never came around to put into a light, with the oldest software.
Not 100% sure if I want to get rid of it, but it has been collecting dust for a year now.

Hi flex -

These are the one's winny made?

I have 2 of them.
IIRC they're still in the bubblewrap.

incoming PM headed your way.

If there is a second one up for grabs I'd sure like to get one?

Thanks to all for the answers :bow:


actually i evaluate all offers, JimmyM, also the used PIR, but for first i need to know some things:

- the PIR's that you have are already well calibrated?

- the microcontroller on the PIR have this number? ATMEGA8 16AU 0537I (looks the thread for the pics)


I've encountered some problems of calibration in my PIR with this microcontroller, my second PIR with the new version of microcontroller ATMEGA8 16AU 0605I is more stable.

Thanks.

I'd have to look at the chip to be sure.
I bought the USB programmer as well, so I've messed with it quite a bit.
It's calibrated well around my battery pack and an output range of 10-13 volts.
The PIR calculates the duty cycle based on the input voltage. I don't believe it reads the output voltage at all.
If you set it for 10V and the battery voltage is read to be 20, it runs at 50%.
It might need re-calibration anyway.
