Hi,

I’m looking for the Murata I2C PIR sensor datasheet: [IRS-D200ST00R1](https://www.digikey.com/en/products/detail/murata-electronics/IRS-D200ST00R1/26763374)

The document provided by DigiKey just has dimmensions and general information. I need information about I2C, etc.

Thanks!!

Thank you, Nick. I’ve been looking for this document for over a week now.

It appears that Murata hasn’t produced any dedicated lens for this specific PIR sensor.

Do you think it might be possible to find a compatible lens from another manufacturer that would allow for easy integration in mass production?

I’m looking for something similar to this lens:
