Mq 135 Gas Sensor Working

This is a robust gas sensor suitable for sensing lpg smoke alcohol propane hydrogen methane and carbon monoxide concentrations in the air if you are planning on creating an indoor air quality monitoring system. Since ao is a varying voltage this pin should be connected to one analog input of a microcontroller the do pin is an open collector digital output but with a pull up resistor onboard that becomes low when the detection level exceeds a predefined level. Now you know quite a bit about mq 135 sensor let s move ahead and learn how to interface the mq 135 with arduino interfacing.

Breath checker or early fire detection system mq2 gas sensor module is a great choice.

Mq 135 gas sensor working.

Normally the atmosphere will contain more oxygen than combustible gases. Give your next arduino project a nose for gasses with the mq2 gas sensor module. The smoke sensor we used is the mq 135 sensor. Try to leak the gas without igniting it near the sensor.

The mq 3 gas sensor has a lower conductivity to clean the air as a gas sensing material. Mq2 is a metal oxide semiconductor type gas sensor. What is mq 135 and how does it work. The operating voltage of this gas sensor is from 2 5v to 5 0v.

The air quality information is readable via the ao pin. The boost converter of the chip mq 3 gas sensor is pt1301. The mq 135 gas sensor module has four pins standard male headers as shown above. The mq 135 gas sensor senses gases like ammonia nitrogen oxygen alcohols aromatic compounds sulfide and smoke.

Simply we have interfaced mq 135 gas sensor module with arduino and 16 2 lcd module for display. What is mq 135 gas sensor and how does it work. Concentrations of gas in the gas is measured using a voltage divider network present in the sensor. The most commonly used chemiresistor is tin dioxide sno2 which is an n type semiconductor that has free electrons also called as donor.

This sensing element is subjected to current through connecting leads. This sensor works on 5v dc voltage. When there is an increase in polluting gases the resistance of the gas sensor decreases along with that. To measure ppm using mq 135 sensor we need to look into the rs ro v s ppm graph taken from the mq135 datasheet.

The ability of a gas sensor to detect gases depends on the chemiresister to conduct current. The gas sensor module consists of a steel exoskeleton under which a sensing element is housed. Smoke detectors are very useful in detecting smoke or fire in buildings and so are the important safety parameters. It can detect gases in the concentration of range 200 to 10000ppm.

As the concentration of gas rises around the sensor the current flow through ammeter increases. Mq 135 gas sensor applies sno2 which has a higher resistance in the clear air as a gas sensing material. If this works your sensor is working normally.
