This semiconductor gas sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10,000 ppm. The sensor's simple analog voltage interface requires only one analog input pin from your microcontroller.
Ready to ship indoor omni-directional platform. This robot uses a trio of mecanum wheels to maneuver in any direction. Great for indoor applications. This is a low run prototype platform heavily discounted. In working condition but support is limited.
