Hi. Can you tell me, please, the name of an humidity sensor and the company that sell it?

I need an humidity sensor with I2C digital output.

Thanks,

Simo.

Look for http://www.sensirion.com/

They have sensors with serial output. Also try 1-wire %RH sensors from

www.maxim-ic.com

Have you ever actually bought the 1-Wire sensor (not the button) from Maxim in recent times ?

They used to be available.

No, I changed to Humirel Sensors HS1101LF type which is capacitive sensor element and I build the remaining electronics for it. I think they are good enough for most of the experiments I do.

I have also used Honeywell Sensors that were conductive film type. For Dallas Sensors, perhaps you can directly get in touch with them at www.maxim-ic.com and they will respond to all queries.
