Me Gas Sensor V1

Me Gas Sensor includes a smoke sensor of type MQ2 which has good repeatability, long-term stability, short response time, and durable working performance. It is often used as a gas leakage monitoring device in family and factory, and suitable for detecting Liquified Natural Gas (LNG), butane, propane, methane, alcohol, hydrogen, smoke, etc. Its black ID means that it has an analog port and needs to be connected to the port with black ID on Makeblock Orion.
