Installation Instructions for the
HIH-4010/20/21 Humidity Sensors
WARNING
PERSONAL INJURY
• DO NOT USE these products as safety or emergency
stop devices or in any other application where failure of
the product could result in personal injury.
• The sensor’s housing does not provide electrical safety
isolation. Mount the sensor in a location where it cannot
be touched, or where a surrounding barrier prevents
human contact.
Failure to comply with these instructions could result in
death or serious injury.
CAUTION
IMPROPER HANDLING
• Do not remove the sensor from its original protective
packaging until it is ready to be installed.
• Do not touch the sensor surface. Use latex finger cots.
Handle the sensor by its package edges or leads.
• Do not allow objects to enter the cavity of the sensor
element.
Failure to comply with these instructions may result in
product damage.
NOTICE
• Under condensing conditions where enough liquid water
forms on the sensor to create a parasitic leakage path, the
HIH-4010/20/21 Series Humidity Sensor produces an
erroneous reading of 0% humidity. If this erroneous
reading is assumed to be correct by your control function,
excess humidity is likely to be introduced into the system.
Once the liquid water evaporates from the sensor and the
environment returns to a non-condensing state, the device
returns to normal functionality.
• Shade the sensor from direct light. Intense direct light can
flood junctions in the CMOS (Complementary Metal Oxide
Semiconductor) device and drive the output signal to the
minimum. This does not harm the sensor or affect
calibration. Proper operation resumes shortly after the
direct light is removed. Ambient scattered light normally
does not affect performance.
• At the end of its working life, dispose the sensor in
accordance with Directive 2002/96/EC (WEEE).

SOLDERING/ASSEMBLY
CAUTION
IMPROPER CLEANING
• Insert and solder the sensor after the PCB cleaning
process.
• Clean sensor with isopropyl alcohol after soldering.
Failure to comply with these instructions may result in
product damage.
CAUTION
IMPROPER SENSOR POSITIONING
• Position the sensor so that its face is exposed to the
atmosphere being monitored.
Failure to comply with these instructions may result in
product damage
Hand soldering is acceptable. If wave soldering is required,
use a no-clean flux. Limit the contact of the flux to the leads
only.
Recommended PC board wave soldering temperature is

o
250 C to 260 C [482 F to 500 F].
MOISTURE SEALING THE LEADS
If, in the presence of intermittent moisture or other
contaminants, there is the possibility of galvanic paths between
the leads, moisture seal the leads and exposed pads.

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.
