HIH-4000 Series
Humidity Sensors
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 ìA, 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.
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.
