Humidity Sensor

[Pon]

Hi,

I am looking for an Humidity Sensor (upto 7.5% RH), which should be
PCB mountable. A tube/duct should be able to connected to it. It has
to sense the humidity of the air on the duct.

Pls giveout your ideas/experiences

It can be done with a simple MEMS capacitor with dielectric tunnels.
We can build approximately 400 at a time. How many do you need?
