An “anti-explosion network” is two layers of fine stainless steel mesh that ensure the heater element inside the sensor does not cause an explosion when sensing flammable gases. Related Questions What is an MQ2 gas sensor? What type of gas…
The MQ2 gas sensor is a heater-driven sensor, which is why it is covered with two layers of fine stainless steel mesh known as an “anti-explosion network”. This ensures that the heater element inside the sensor does not cause an…
The SnO2 semiconductor layer in the MQ2 gas sensor is heated to a high temperature, allowing oxygen to be adsorbed on the surface. When the air is clean, electrons from the conduction band of tin dioxide are attracted to oxygen…
The output of the MQ2 gas sensor changes depending on the gas it is exposed to. When exposed to reducing gasses, the surface density of adsorbed oxygen decreases, allowing electrons to be released into the tin dioxide and allowing current…
When a cloud of smoke is created using an incense stick near the MQ2 gas sensor, the second LED will glow green. Related Questions What is an MQ2 gas sensor? What type of gas sensor is used in fire alarm…

When exposed to smoke, the MQ2 gas sensor gives a high output voltage, and when there is no smoke, it gives a low output voltage. Related Questions What is an MQ2 gas sensor? What type of gas sensor is used…
When the MQ2 gas sensor is powered up, the LED will glow red. When no gas is detected, the output LED will remain turned off, which means the digital output pin is 0V. Related Questions What is an MQ2 gas…
The MQ2 gas sensor can detect LPG, smoke, alcohol, propane, hydrogen, methane, and carbon monoxide concentrations ranging from 200 to 10,000 ppm. Related Questions What is an MQ2 gas sensor? What type of gas sensor is used in fire alarm…
The MQ2 gas sensor operates by heating a SnO2 semiconductor layer. When the air is clean, electrons from the conduction band of tin dioxide are attracted to oxygen molecules, forming a potential barrier which makes the SnO2 film highly resistive.…
