MQ-135 Sensor Description:
MQ135 gas sensor is sensitive material used in clean air, low conductivity tin dioxide (SnO2).
When the sensor is kept in their environment
The contaminated gas, the conductivity of the sensor with the air pollution gas concentration increases.
Using a simple circuit can be changes in the conductivity
Of the concentration of the gas is converted to the corresponding output signal.
MQ135 sensor for ammonia, sulfide, benzene vapor high sensitivity, smoke and other harmful monitor
is also very satisfactory. This sensor can detect a
Measuring a variety of harmful gases, is a low-cost sensors for a variety of applications.
Module Applications:
For home, environmental harmful gas detection device, suitable for ammonia, aromatic compounds, sulfur,
benzene vapor, smoke and other gases harmful gas detection, gas sensors tested concentration range: 10 to 1000ppm.
