Gas Sensor Semiconductor Chip from Japan
A metal-oxide-semiconductor (MOS) gas sensor chip that detects reducing or oxidizing gases by measuring changes in electrical conductivity of a semiconductor film. It is a semiconductor-based transducer because it converts a chemical phenomenon (gas concentration) into an electrical signal, and it is sold as a discrete component for air quality monitors and industrial safety devices.

Import Tips
• Ensure the chip is not combined with a microcontroller or signal-conditioning circuitry that would make it an integrated circuit
• Provide the manufacturer's datasheet showing the semiconductor sensing element to justify classification
• If the sensor is part of a complete gas detector with alarms, that product belongs in Chapter 90
