process for a long time under abnormal operating conditions.

Avoid placing components on a long-term condensation and dry conditions and the following

environment.

A, salt spray

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

Recommended Storage Environment

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

2. Effects of exposure to chemical substances

Capacitive humidity sensor sensing layer will be disturbed chemical vapors, chemical diffusion

layer in the sensor may cause drift and measurement sensitivity. In a clean environment, slowly

release contaminants out. The recovery process described below to accelerate the process. High

concentrations of chemical pollution can cause damage to the sensor sensing layer completely.

3. Temperature Effect

Relative humidity of the gas, is largely dependent on temperature. Therefore, when measuring

the humidity should be possible to ensure that the humidity sensor works at the same temperature. If

you share a printed circuit board with electronic components heat released in the sensor should be

installed as far as possible away from the electronic components, and installed at the bottom of the

heat source, while maintaining a well-ventilated enclosure. To reduce the thermal conductivity sensor

and a copper plating layer of the printed circuit board should be as minimal other portions, and

leaving a gap between them.

4. Light effects

Prolonged exposure to sunlight or strong ultraviolet radiation, will reduce performance.

5. Recovery process

Placed under extreme operating conditions or chemical vapor sensors, through the following

process, you can return it to the state calibration. 2 hours at 45℃ and < 10% RH humidity

conditions(Hong Gan); then at 20-30 ℃ and> 70% RH humidity under conditions remain more

than 5 hours.

6. Wiring Precautions

Affects the communication quality of the signal wire distance and communication quality, we

recommend using a high quality shielded cable.

7. Soldering Information

Manual welding, at a temperature of 300 ℃ maximum contact time must be less than 10

seconds.

8. Product upgrades

For details, please consult our technical department.
