Introduction:

The preadjusted, capacitive E+E humidity sensor renders elaborate humidity adjustment unnecessary.
Temperature is measured by means of a high precision thin-film element – a prerequisite for precisely determining dew point.
The SMD housing provides maximum mechanical sensor protection while permitting a standard reflow process. A protective film applied to the active surface of the humidity sensor provides effective protection against soiling such as dust, mineral salts or other deposits.

Depending on accuracy requirements and existing electronics, various cost-effective evaluation circuits are available. This application note will help you find the most suitable circuitry for your application.
