Science, technology, engineering, and math are the foundations of our daily lives. They are the tools that professionals use to get things done and get them done right. That’s just one reason that STEM education is so important. Over the past few decades, a sea-change in educational theories has swept through academic institutions. Old ideas
MQ131 Ozone Gas Sensor Module is a compact board based on the MQ-131 sensor. It is equipped with a very wide range sensitivity to ozone which able to detect ozone concentration up to (10～1000ppb) in ambient air. The tin dioxide (SnO2) is the sensor's sensitive material, has a low conductivity (high
01-11-2017· DESCRIPTION Sensitive material of MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
