Features of electronic humidity sensor:

The electronic humidity meter sensor has been developed rapidly in recent decades, especially in the past 20 years. The humidity sensor manufacturer must use a standard humidity generator to calibrate one by one before the product leaves the factory. The accuracy of the electronic humidity sensor can reach 2 percent to 3 percent RH.

In actual use, due to the influence of dust, oil pollution and harmful gases, it will be aging and the accuracy will decrease after a long time of use. The annual drift of the humidity sensor is generally about ±2 percent or higher. Under normal circumstances, the manufacturer will indicate that the effective use time of one calibration is 1 year or 2 years, and it needs to be re-calibrated after the expiration.

The accuracy level of the electronic humidity sensor should be judged in combination with its long-term stability. Generally speaking, the long-term stability and service life of the electronic humidity sensor are not as good as that of the wet and dry bulb humidity sensor.

The humidity sensor uses semiconductor technology, so it has requirements for the ambient temperature used. Exceeding the specified operating temperature will cause damage to the sensor.

Therefore, the electronic humidity sensor humidity measurement method is more suitable for use in clean and normal temperature occasions.
