SMD Humidity Sensors are Reliable and Proven

Honeywell’s broad range of sensors provides the reliability and proven track record required for medical installations. The company’s custom and standard sensors are backed by a robust line-up of accessories and components delivered with high levels of engineering, technical and applications knowledge.

The company’s products offer a wide range of sensing technologies, operating specifications, accuracies, temperature ratings, packaging, connectors and power requirements.



The HIH-4030, for example, is a covered integrated circuit Relative Humidity (RH) sensor. The HIH-4031 includes a hydrophobic filter, allowing it to be used in environments that are prone to condensation, dust, dirt, oils and contact with chemicals. They deliver instrumentation-quality RH sensing performance in a competitively priced, solderable SMD (Surface Mount Device).
