General Description

Alcohol sensor is a miniature metal oxide semiconductor gas sensor based on MEMS micro hotplate technology for detection a wide rang of organic solvent vapor in air.

Sensor production combined with silicon substrate MEMS technology, thin film technology, thick film technology and ceramic packaging technology.

The gas sensitive layer is deposited at the top of the hotplate and interdigitated electrodes, resulting in a conductivity dependent on the concentration of harmful gases.

Features:

High sensitivity and large dynamic range to organic

solvent vapor ( 1~1000ppm )

Quick response (~10Sec.)

Very low power consumption ( 40~42mW )

Small size  ( 3.8mm × 3.8mm × 1.5mm )

Long operating life ( ~10 Years )

Reflow soldering

Applications:

Organic solvent vapor leakage alarm

Alcohol detection

IoT, wearable devices, smart home
