HONEYWELL HIH-4000-003 Humidity Sensor 3.5% SIP 5.8V

The HONEYWELL HIH-4000-003 is a high-performance, instrumentation-grade humidity sensor designed specifically for demanding original equipment manufacturer (OEM) applications. Its near-linear voltage output relative to percentage relative humidity (%RH) allows for direct input to a microcontroller or other logic device, simplifying system design and integration.

A standout feature is its exceptionally low power consumption, with a typical current draw of only 200µA. This makes it an ideal choice for battery-operated systems, portable devices, and other applications where energy efficiency is paramount. The sensor's laser-trimmed thermoset polymer capacitive sensing element, coupled with on-chip integrated signal conditioning, provides reliable and accurate measurements.

Key Benefits

• Tight Interchangeability: Laser trimming ensures consistent performance from sensor to sensor, which can significantly reduce or even eliminate production line calibration costs for OEMs.
• Robust Construction: The sensing element features a multilayer construction housed in a moulded thermoset plastic casing, offering excellent resistance to common environmental hazards including condensation, dust, dirt, oils, and many chemicals.
• Reliable Performance: Enjoy stable, low-drift readings and a fast response time, delivering precision you can count on in variable conditions.
