SEN0469, SEN0567 Specification Sheets

Dear DFRobot Forum, 

I have a question regarding SEN0469 and SEN0567 products. I need to know their unit prices, repeatabilities, sensitivities, data types (digit/model), cross-sensitivities and alternative model types. I also cannot find their specification sheets on their pages of the website.

Thank you for your help and consideration. 

Kind regards,

Darina Bekenova
