The Grove multichannel gas sensor is an environment sensor with a built in MiCS-6814 which can detect many different types of harmful gases. All the gases can be measured simultaneously which can help you to monitor the concentration of the gases.

This sensor is part of the Grove system, you can plug it onto the Base shield and it will work with Arduino directly without any jumper wires. The interface is I2C, plug it into the I2C port of Base shield and start working with it straight away.
