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.
This is a ROS programmable autonomous SLAM robot prebuilt kit that can be controlled via Gamepad. The MarvelMind IPS (Indoor Positioning System) provides indoor navigation. ODROID-XU4 SBC provides the most flexible platform possible.
