Overview
It can detect combustible Carbon Monoxide, Coal Gas and Liquefied Gas. The sensitivity can be adjusted by the potentiometer.
Hardware Overview
This is an Analog output sensor. It needs to be connected to any one Analog socket in Grove Base Shield. It is possible to connect the Grove module to Arduino directly by using jumper wires. When doing so, please refer to the connection table below:

The output voltage from the Gas sensor increases when the concentration of gas. Sensitivity can be adjusted by rotating the potentiometer.
Please note that the best preheat time for the sensor is 24 hours and above.
Note: Hot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.

Get Inspired
While touchscreens are nice, wouldn’t it be even better if you could simply wave your hand to your computer to get it to do what you want? That’s the idea behind this Iron Man-inspired gesture control device by B. Aswinth Raj. The DIY system uses an Arduino Nano mounted to a disposable glove, along with hall effect sensors, a magnet attached to the thumb, and a Bluetooth module. This smart glove uses the finger-mounted sensors as left and right mouse buttons, and has a blue circle in the middle of the palm that the computer can track via a webcam and a Processing sketch to generate a cursor position. You can see it demonstrated in the video below, drawing a stick man literally by hand, and also controlling an LED on the Nano. Check out this write-up for code and more info on the build!
