HIH-4000 Series Humidity Sensor

specifically for high volume OEM (Original Equipment

Manufacturer) users. Direct input to a controller or other device

is made possible by this sensor’s 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.

         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.
