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 (drying) under 10% RH humidity
conditions; then at 20-30 ℃ and> 45 ℃ and humidity under 70% RH conditions were maintained for
more than 5 hours.
6. Wiring Precautions
DATA signal wire quality will affect the communication 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
