Ethanol Sensor SMD1005 Low Power High Precision Surface mounted Alcohol Gas Sensor
Core Features:
- Advanced MEMS Technology: Adopts MEMS manufacturing process, featuring a sturdy structure and strong shock resistance, which can adapt to the use environment of various portable electronic devices.
- Outstanding Basic Performance: It has the advantages of small size (0.5cm×0.5cm, weight 5g), low power consumption and high sensitivity. Its resolution can reach 1ppm, which can accurately detect trace ethanol gas in the air.
- Efficient Detection Capability: Possesses fast response and recovery speed. It can quickly convert the change of ethanol concentration into electrical signal feedback, and the drive circuit required for work is simple, which reduces the difficulty of equipment integration.
- Stable and Durable Operation: It maintains stable performance within the rated operating temperature and humidity range, and has a long service life, which meets the long-term use needs of consumer electronic products.
Typical Applications:
- Consumer Electronics: Integrated into consumer electronics such as mobile phones, computers and vehicle-mounted devices to detect ethanol vapor in the surrounding environment of the equipment.
- Alcohol Detectors: Serves as a core component of alcohol monitors, suitable for scenarios such as daily personal alcohol testing.
- Occupational Safety Monitoring: Applied in the drunk supervision equipment for motor vehicle drivers and staff engaged in high-risk operations, helping to avoid safety hazards caused by alcohol intake during work.
