8、Application of information

1. Work and storage conditions

Outside the sensor the proposed scope of work may lead to temporary drift of the signal up to 300% RH. Return to

normal working conditions, sensor calibration status will slowly toward recovery. To speed up the recovery process

may refer to "resume processing". Prolonged use of non-normal operating conditions, will accelerate the aging of the

product.

Avoid placing the components on the long-term condensation and dry environment, as well as the following

environment.

A, salt spray

B, acidic or oxidizing gases such as sulfur dioxide, hydrochloric acid

Recommended storage environment

Temperature: 10 ~ 40 ℃ Humidity: 60% RH or less

2. The impact of exposure to chemicals

The capacitive humidity sensor has a layer by chemical vapor interference, the proliferation of chemicals in the

sensing layer may lead to drift and decreased sensitivity of the measured values. In a pure environment, contaminants

will slowly be released. Resume processing as described below will accelerate this process. The high concentration of

chemical pollution (such as ethanol) will lead to the complete damage of the sensitive layer of the sensor.

3. The temperature influence

Relative humidity of the gas to a large extent dependent on temperature. Therefore, in the measurement of humidity,
