Description
 
H2 sensor is a miniature metal oxide semiconductor gas sensor based on MEMS micro hotplate technology for detection a wide rang of H2 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 H2 ( 0.1~1000ppm )
 Quick response (~10Sec.)
 Very low power consumption ( ~35mW )
 Small size ( 3.8mm × 3.8mm × 1.5mm )
 Long operating life ( ~10 Years )
 Reflow soldering

Applications:

 Hydrogen leakage detection
 Lithium battery thermal runaway monitoring
 IoT, wearable devices, smart home
