DESCRIPTION

· Honeywell introduces the HIH-4030/4031 Series, an SMD humidity sensor line for high-volume OEM use.

· Features near-linear voltage output for direct controller input, ideal for low-power, battery-operated systems.

· HIH-4030 is a covered IC humidity sensor; HIH-4031 includes a hydrophobic filter for condensing environments.

· Utilizes a laser-trimmed, thermoset polymer capacitive sensing element with on-chip signal conditioning.

· Offers excellent resistance to environmental hazards like condensation, dust, and chemicals.

FEATURES

· Packaged on tape and reel for automated manufacturing (1,000 units per reel).

· Molded thermoset plastic housing ensures durability.

· Near-linear voltage output relative to %RH enhances accuracy.

· Laser-trimmed for tight sensor interchangeability, reducing calibration needs.

· Low power consumption (200 μA typical) suitable for battery-powered systems.

· Fast response and stable, low-drift performance in various conditions.

· Chemically resistant construction for robust application use.

APPLICATIONS

· Refrigeration and HVAC systems for precise humidity control.

· Medical equipment requiring reliable humidity sensing.

· Industrial drying processes and metrology applications.

· Battery-powered systems due to low power requirements.

· OEM assemblies in industrial, commercial, and medical sectors.
