HIH-4010/4020/4021

Series

Humidity Sensors

DESCRIPTION

The HIH-40104020/4021 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-4010/4020/4021 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-4010/4020/4021 Series delivers instrumentation-

quality RH (Relative Humidity) sensing performance in a

competitively priced, solderable SIP (Single In-line Package).

The HIH-4010 is an uncovered integrated humidity sensor, the

HIH-4020 is a covered integrated circuit humidity sensor, and

the HIH-4021 is a covered, condensation-resistant, integrated

circuit humidity sensor. All three products are available in two

lead space configurations.

The RH sensor is 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

wetting, dust, dirt, oils and common environmental chemicals.

Both products are available in two lead spacing configurations,

as well as with or without calibration and data printouts.

Specific Notes:

1. For HIH-4010/20/21-003/004 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.
