The hih-4000 series moisture sensors are OEM's designed for mass production
The voltage output of this sensor can be directly input to the controller or other
Device. The hih-4000 series moisture sensor is ideal for removal of 200 a current
For low lead, battery powered systems. Good sensor interchangeability reduces or eliminates OEM
Production calibration cost. Single sensor calibration data can be provided.
The hih-4000 series moisture sensor serves as a low-cost, solderable single in-line package
Pieces (sip) provide the relative humidity (rh) sensing performance of the meter measurement quality. The rh sensor can be used in two
It is a thermoplastic capacitance sensing element with spacing between the leads, and is provided within the chip
The multi-layer structure of the sensing element is unfavorable to the application environment, such as humidity.
Dust, dirt, oils and chemicals commonly found in the environment have the best resistance.

1. The sensor shall not be exposed to condensation.
2. Exposure to liquid water will cause the sensor output indicator to be 0%rh.
3. The sensor belongs to light sensitive equipment. For the best performance, the sensor should be shielded to avoid strong light.
4. Exposure to >90%rh can cause 3%rh reversible drift.
5. The connection of the sensor shall be protected against static electricity up to 15kv.
6. The sensor output is proportional to the supply voltage.
