HIH-4000 series measuring humidity sensor is designed for mass production of an original equipment manufacturer (OEM)

Designed for users. using linear voltage output of the sensor can be entered directly into the controller or other

Devices. need only take the 200 μA current HIH-4000 series measuring humidity sensor can be ideally

For low lead, battery-powered system. good interchangeability of the sensor reduces or eliminates the OEM

Production verification costs. can supply a single sensor calibration data.

HIH-4000 series measuring humidity sensor as a low cost, but a single dip soldering set

(SIP) provides the meter measuring the quality of relative humidity (RH) sensor performance. RH sensor can be used in two

Lead spacing between the assigned amount, it is a thermoset polymer capacitance sensor chip

Signal processing functions. the multilayer structure of the sensing element of adverse environmental factors, such as humidity,

Dust, dirt, oils and common chemicals in the environment with the best resistance.

Specifications include areas outside the scope of the work recommended by the test data.

Specifications for recommended working areas, only.

Notes:

1. the sensor in an environment not exposed to condensation.

2. exposed to liquid water will cause the sensor indicated as 0%RH.

3. the sensors are of the light sensitive equipment. for best performance, should shield the sensor, avoiding the glare.

4. in an environment exposed to >90%RH reversible drift can cause 3%RH.

5. sensor of electrostatic sensor connections should be protected, up to 15kV.

6. the sensor's output and supply voltage is proportional to.
