How to choose a gas sensor ?
Grove – Multichannel Gas sensor is a environment detecting sensor with a built in MiCS-6814 which can detect many unhealthy gases. 3 gases can be measured simultaneously due to its three channels, so it can help you to monitor the concentration of more than one gas.
This sensor belongs to the Grove system, and you can plug it onto the Base shield and work with Arduino directly without any jumper wires. The interface is I2C, so plug it onto the I2C port of Base shield, then you can start to work on it.
Tip
We've released the Seeed Gas Sensor Selection Guide, it will help you choose the gas sensor that best suits your needs.

I try to connect this module to Wio Tracker GPS, using the provided multi-channel gas library. I found out that the board (the Wio Tracker) stop working. the loop function stop working when gas.begin() is used. when comment it out. it start working again. Does the library of multi-channel gas has compatibility with Wio Tracker?Question by: Luqman Hakim on 2019-04-09 14:46:52

Hi Nick~Theoretically you can use it with LCPExpresso.However we only privode library for Arduino.I am not sure the Arduino Library is compatible with LPCXpresso IDE.If not you need to write the library yourself.I recommend you use Seeeduino V4.2 with this sensor.It will be simple and easy.Regards

Hi,friend! We only provide software library or code examples for Arduino platform in most cases. Hence,if you want to attach it to the Raspberry,you have to write your own software library.
