Relative Humidity Measurement System Using AD7745 24-Bit Capacitance-to-Digital Converter with Temperature Sensor

Relative Humidity Measurement System of 2-Chip Circuit provides a contactless, capacitive based, relative humidity (RH) measurement solution with 2% relative humidity accuracy from 0% RH to 100% RH and replaces bulky hygrometer based methods. The circuit is ideal for applications where accurate, temperature controlled, noncontact humidity measurements are critical, such as HVAC, telecommunication cabinets, infant incubators and other industrial or medical applications
