There are too many questions. How bad is it? Does it smell? Do I want to run away? Start with the ArduSensor Fart which is yes, you guessed it, a fart/methane detector.

Warning:  This type of gas sensor will mostly sense changes in values, but not precise methane concentration.

Note: This ArduSensor will only fit on the end spot of the ArduSensor Shield.

What is Qtechknow?

Our kits and products will enable you to have success in electronics. We make soldering kits for beginners, breakout boards for intermediate users, and development boards for more advanced users. We also have cool starter kits (ArduSensors) that allow you to focus on software for the Arduino as well as many others. The Arduino is a mini-computer that can execute simple (and complex) tasks, such as reading a sensor and showing the value of the sensor on an LED light bar graph. This is one of the most simple tasks that an Arduino can do, the highest power Arduino can even turn into an Android phone, with the extra accessories. Also, the CEO of Qtechknow is 17 years old!
