Operating Note:
* Please do not put the module in organic solvent (include silica gel and other cementing compound), painting,
medicament, oils and fuels, high concentration gas etc.
* The module is an ESD-sensitive module, so we recommend that ESD protection equipment be used
during usage and assembly the module in the application products.
* The accuracy in the data sheet is date before delivery. If with long term storage, after re-calibration, the
accuracy can be recovered.
* Keep the module out of the heat source, avoid direct sunlight and other heat radiations.
*Periodic calibration is necessary, no more than 6 months is recommend.
* Please warm up for 5 min before first using.
* Please do not use the module related with personal safety.
* Please do not install the module in the severe convection
environment.
* Please do not put in the module in high concentration organic gas
for long time
