General Description

CH4 sensor is a miniature metal oxide semiconductor gas    sensor based on MEMS micro hotplate technology for detection a wide rang of CH4  gas 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 to CH4 ( 50~15000ppm )

Quick response (~10Sec.)

Very low power consumption ( ~60mW )  

Small size  ( 3.8mm × 3.8mm × 1.5mm )

Long operating life ( ~10 Years )

Reflow soldering

Applications:

Natural gas leakage alarm

Portable detector

IoT, wearable devices, smart home
