HIH-4010/4020/4021
Series
Humidity Sensors
DESCRIPTION
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 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.
The RH sensor is a laser trimmed, thermoset polymer
capacitive sensing element with on-chip integrated signal
conditioning.
Tight sensor interchangeability reduces or eliminates OEM
production calibration costs. Individual sensor calibration data
is available.
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.
The HIH-4010/4020/4021 Series delivers instrumentation-
quality RH (Relative Humidity) sensing performance in a
competitively priced, solderable SIP (Single In-line Package).
