Datasheet - SHT40I-HD1B-R2

COO (Country of Origin):: CH

The Sensirion Sensors from the SHT4xI analogue sensor family, currently represented by the SHT40I analogue, deliver an analogue voltage output with several available output characteristics. An optional periodic variable power heater allows for operation in highly demanding environments, such as constant high humidity and condensing atmospheres. The four pin dual flat no leads package is suitable for surface mount technology processing. Options equipped with patented filter membranes enable operation in harshest environments.

Fully functional in condensing environment

Mature technology from global market leader
