Description
of Sensor Characters
C3H8 Air CH4 Alcohol Smoke
Concentration
Fig3.Typical Sensitivity Curve
The ordinate is resistance ratio of the sensor (Rs/R0), the abscissa is concentration of gases.Rs means resistance in target gas with different concentration, R0 means resistance of sensor in clean air.All tests are finished under standard test conditions.Fig4.Typical temperature/humidity characteristics
The ordinate is resistance ratio of the sensor (Rs/Rso).Rs means resistance of sensor in 2000p
Features
- It has good sensitivity to propane, smoke &etc in wide range, and has advantages such as long lifespan,
low cost and simple drive circuit &etc. Main.
