In the figure, Rs represents the resistance value of the sensor in different concentrations of gas, and R0 represents the resistance value of the sensor in clean air. Test the sensitivity of different types of interference gases separately. All tests in the figure are completed under standard test conditions.

In the figure, Rs represents the resistance value of the sensor in different concentrations of gas, and R0 represents the resistance value of the sensor in clean air. The test gas was 10 ppm of NH 3. All tests in the figure are completed under standard test conditions. In the figure, Rs indicates the stable resistance of the sensor in ammonia at 30ppm concentration under different temperature and humidity conditions, and R 0 indicates the stable resistance of the sensor in ammonia at 30ppm concentration under 20 ° C and 55% RH humidity conditions.
