HIH-4030/31 Series

Humidity Sensors

DESCRIPTION

Honeywell has expanded our HIH Series to include an SMD

(Surface Mount Device) product line: the new HIH 4030/4031.

The HIH 4030/4031 complements our existing line of non-SMD

humidity sensors. SMD packaging on tape and reel allows for

use in high volume, automated pick and place manufacturing,

eliminating lead misalignment to printed circuit board through-

hole.

The HIH-4030/4031 Series Humidity Sensors are designed

specifically for high volume OEM (Original Equipment

Manufacturer) users.

Direct input to a controller or other device is made possible by

this sensor’s near linear voltage output. With a typical current

draw of only 200 μA, the HIH-4030/4031 Series is often ideally

suited for low drain, battery operated systems.

Tight sensor interchangeability reduces or eliminates OEM

production calibration costs. Individual sensor calibration data

is available.

The HIH-4030/4031 Series delivers instrumentation-quality RH

(Relative Humidity) sensing performance in a competitively

priced, solderable SMD.

The HIH-4030 is a covered integrated circuit humidity sensor.

The HIH-4031 is a covered, condensation-resistant, integrated

circuit humidity sensor that is factory-fitted with a hydrophobic

filter allowing it to be used in condensing environments

including industrial, medical and commercial applications.

The RH sensor uses a laser trimmed, thermoset polymer

capacitive sensing element with on-chip integrated signal

conditioning.

The sensing element's multilayer construction provides

excellent resistance to most application hazards such as

condensation, dust, dirt, oils and common environmental

chemicals.

Sample packs are available. See order guide.

Specific Notes:

1. Can only be achieved with the supplied slope and offset. For

HIH-4030/31-003 catalog listings only.

2. Includes testing outside of recommended operating zone.

3. Includes testing for recommended operating zone only.

4. Device is calibrated at 5 Vdc and 25 ºC.

5. Non-condensing environment. When liquid water falls on the

humidity sensor die, output goes to a low rail condition

indicating no humidity.

General Notes:

• Sensor is ratiometric to supply voltage.

• Extended exposure to >

90% RH causes a reversible

shift of 3% RH.

• Sensor is light sensitive. For best performance, shield

sensor from bright light.
