I am unable to find the resistors for this project?

Hi,

I am very new and wanted to follow this project: https://www.instructables.com/id/The-CANARY-Arduino-Based-NO2-Sensor-and-Mapper/ .

The resistors required are: "Resistors 132Ohm (2 264Ohm used in paralell) and 22kOhm"

I found the 22kOhm resistors: https://cpc.farnell.com/multicomp/mf50-22k/resistor-0-5w-1-22k/dp/RE05048?st=22k%20resistors .

However, I am unable to find the "2 264Ohm" resistors anywhere online. Am i missing something?

Any help at this point would be extremely helpful and thank you very much in advance.

Kind regards,

Quick update: I did find a 264Ohm resistor before, it is the only one I found, however, it looks like this: https://eu.mouser.com/ProductDetail/KOA-Speer/RN73H1ETTP2640F25?qs=sGAEpiMZZMtlubZbdhIBIJxhl26W3hdIcsdyOrJiOVQ%3D and does not look like the one the Instructables person has in the picture. Hope this helps!

Any combination of resistors equivalent to about 131 Ohms will work, like 100+33 in series.

More information is available in the MICS-2714 datasheet.

You are amazing thanks!

Or just a 130 ohm resistor, being one of the E24 resistor values.

Much easier to see that 120 ohm and 12 ohm in series,
or 220 ohm and 330 ohm in parallel, is exactly 123 ohm.
