What are MQ sensors?

What are MQ sensors?

Introduction. MQ gas sensors are a family of sensors which are used to detect a wide variety of gases like alcohol, smoke, methane, LPG, hydrogen, NH3, Benzene, Propane etc. These sensors are made up of electrode which is coated with a sensing material, and it is heated to make it more reactive and sensitive.

What does IBM MQ mean?

message queue
Websphere MQ, formerly known as MQ (message queue) series, is an IBM standard for program-to-program messaging across multiple platforms. Websphere MQ is sometimes referred to as message-oriented middleware (MOM).

What does MQ2 sensor detect?

MQ2 is one of the commonly used gas sensors in MQ sensor series. MQ2 Gas sensor works on 5V DC and draws around 800mW. It can detect LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations anywhere from 200 to 10000ppm.

Why is MQ used?

Applications communicate with each other by exchanging messages on queues. The main use of IBM MQ is to send or exchange messages. One application puts a message on a queue on one computer, and another application gets the same message from another queue on a different computer.

Can MQ2 detect smoke?

What does MQ-7 measure?

This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere from 10 to 500ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance.

What kind of gas does the mq-6 gas sensor measure?

Alternative MQ Gas sensors Sensor Name Gas to measure MQ-5 Natural gas, LPG MQ-6 LPG, butane MQ-7 Carbon Monoxide MQ-8 Hydrogen Gas

What is the value of Ro and Ro in mq-6?

Basically we need to look into the (Rs/Ro) VS PPM graph given in the MQ-6 datasheet, and also shown below. The value of Ro is the value of resistance in fresh air and the value of Rs is the value of resistance in Gas concentration.

Can a gas sensor be used with a microcontroller?

When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can be used with most common microcontrollers. So if you are looking for a sensor to detect or measure gasses like LPG, or methane with or without a microcontroller then this sensor might be the right choice for you.
