Honeywell HIH-4000-003
DESCRIPTION
The HIH-4000 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-4000 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.
FEATURES
Molded thermoset plastic housing
Near linear voltage output vs % RH
Laser trimmed interchangeability
Low power design
Enhanced accuracy
Fast response time
Stable, low drift performance
Chemically resistant
The HIH-4000 Series delivers instrumentation-quality RH
(Relative Humidity) sensing performance in a competitively
priced, solderable SIP (Single In-line Package).
Available in two lead spacing 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.
POTENTIAL APPLICATIONS
Refrigeration equipment
HVAC (Heating, Ventilation and Air Conditioning)
equipment
Medical equipment
Drying
Metrology
Battery-powered systems
OEM assemblies

Specific Notes:
General Notes:
1. Can only be achieved with the supplied slope and offset.
Sensor is ratiometric to supply voltage.
For HIH-4000-003 and HIH-4000-004 catalog listings only.
Extended exposure to >90% RH causes a reversible shift
2. Device is calibrated at 5 Vdc and 25 ºC.
of 3% RH.
3. Non-condensing environment.
Sensor is light sensitive. For best performance, shield
sensor from bright light.
