Methane gas sensor S1008Y

semiconductor

CH4 sensor is a miniature métal oxide semiconductor gas sensor based on MEMS micro hotplate technology for détection a wide rang of CH4 gas in air. Sensor production combined with Silicon substrate MEMS technology. thh 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 dépendent on the concentration of harmful gases. Features: >High sensitivity to CH4 ( 5CM5000ppm ) >Quick response (~10Sec.) >Verylow power consumption ( ~60mW ) >Smallsize (3.8mm x 3.8mm x 1.5mm) >Long operating life (-10 Years ) >Reflow soldering Applications: >Natural gas leakage alarm >Portable detector >loT. wearable devices. smart home Remarks: 1,Rq is tested under standard environmental conditions, i.e., in a clean air with a temperature of 25 ± 3 *C and a humidity of 50 ± 10%. 2,Slk is defined as Rq/Rq, Rq is the sensor résistance in the air of 1000 ppm CH4 concentration. 25 ± 3 °C, 50 ± 10%. 3,The response time and recovery time is defined as the time interval from the contact the specified gas concentration to the 70% of the stable résistance variation. 4,Rh is measured in the condition of heating power 60mW. and will change with heating power changes. This feature can be used to do temperature
