Precautions:
1. Modules should avoid contact with organic solvents, coatings, chemicals, and oils. 2. Do not apply the module to systems involving personal safety. 3. Do not install the module in a strong air convection environment for use. 4. The module should not withstand excessive impact or vibration, and should not produce shaking during use, otherwise the returned values will be inaccurate. 5. Please strictly supply power to the module according to its supply voltage. Voltage exceeding 5.5V can cause irreversible damage to the module. 6. Do not place the module in a strong air convection environment for use. 7. Do not place the mold in high concentration organic gas for a long time.
