HIH-4030/31 Series
Humidity Sensors
DESCRIPTION
The HIH-4030/4031 Series delivers instrumentation-quality RH
(Relative Humidity) sensing performance in a competitively
priced, solderable SMD.
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 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 HIH-4030/4031 Series Humidity Sensors are designed
specifically for high volume OEM (Original Equipment
Manufacturer) users.
The RH sensor uses a laser trimmed, thermoset polymer
capacitive sensing element with on-chip integrated signal
conditioning.
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.
The sensing element's multilayer construction provides
excellent resistance to most application hazards such as
condensation, dust, dirt, oils and common environmental
chemicals.
Tight sensor interchangeability reduces or eliminates OEM
production calibration costs. Individual sensor calibration data
is available.
Sample packs are available. See order guide.
