recovery process can be found in "recovery process." The use of the product will accelerate the aging
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.
