MQ4 Methane Gas Sensor Pinout, Datasheet, Features, …
20181002· The connections of MQ4 Gas Sensor Module are very simple. They are made as follows: VCC to 5V; GND to GND; AO to AnalogO; DO to DigitalO ; Using a MQ sensor and detecting the gas is quite easy. You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas is …
Pololu Methane Gas Sensor MQ4
The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Please read the MQ4 datasheet (161k pdf) for more information about the sensor.

Understanding a Gas Sensor | Jaycon Systems
20160509· The data for gas concentration only ranges from 200 ppm to 10000 ppm. Even though the relation between resistance ratio and gas concentration may seem linear, in reality, it is not. First of all, we will treat the lines as if they were linear. This way we can use one formula that linearly relates the ratio and the concentration. By doing so, we can find the concentration of a gas at any ratio ...
