The MQ Gas Sensor checklist
The MQ Gas Sensor Checklist!
“MQ” Gas Sensors are one of the most reliable Gas sensors that you can use to add gas sensing capabilities in your project. These gas sensor modules are used in many projects and industrial applications. If you are like us, having different kinds of sensors attached to our projects makes it more challenging and useful. This will also make your project more reliable and feature rich.
Below are compiled list for the many different kinds of sensors that are used in many projects and products with their individual gas sensing capabilities and working electrical voltages. We have some of them and some have not been stocked yet. If you need one of them hit us in our contact info and we’ll surely get one for you!
