In order to read the data that an MQ sensor acquires we first need an MQ sensor. There are four different sensors OLIMEX distributes. The hardware and software setup of each of them is identical. The power consumption also. However, each of them is suitable for the detection of a different set of substances in the air. Each of the sensors has own its web page. SNSMQ2 is a sensor that detects ...

20170501· Second, the configuration I''m using is a resistor that goes from the power rail to the 5V input on the mq sensor. this resistor is in series with another resistor that is connected to the A0 pin on the sensor. Am I close to correct configuration or completely off? Reply Delete. Replies. Davide Gironi August 9, 2017 at 9:31 PM. Hello, the pull up it is used to read a resistance, here is the MQ ...

20210613· [MQ131 sensor output value] The sensitivity characteristic curve of the MQ131 sensor is as follows. Typical sensitivity curve for the MQ131 sensor • This is a graph of the gas concentration versus Rs/R0 in ppb. • The yaxis is the resistance ratio (Rs / R0) of the sensor. • The xaxis is the value of the low concentration of ozone gas. The low concentration range is 10 to 1000 ppb ...

A small compact sensor for easy assembly in DIY projects. MQ4 Working Principle. As soon as the module is powered, the power LED lights up. The MQ4 works by sensing the methane concentration in the air. The analog pin of the sensor then generates an analog signal proportional to the amount of CH4 in the air. We can measure the analog output ...
