Precautions

• Avoid contact of the smoke sensor module with organic solvents (including silicone and other adhesives), paints, chemicals, oils, and high-concentration gases.
• The sensor module should not be subjected to excessive impact or vibration.
• The module must be preheated for at least 5 minutes before initial power-up.
• Do not use this module in systems involving personal safety.
• Do not install the module in environments with strong airflow.
• Do not expose the gas module to high-concentration organic gases for extended periods.
• Strictly follow the specified power supply voltage when supplying power to the module. Voltages exceeding 5.5V can cause irreversible damage to the module.
