MQ-6 Gas Sensor

The MQ-6 Gas Sensor is a passive, analog or power part in the LabWired part catalog. Its catalog type is mq-6. It connects to the MCU over Analog (ADC). The catalog gives a supply range of 5 V. It has 4 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.

How to simulate the MQ-6 Gas Sensor in LabWired

Open the Playground at app.labwired.com and place an MCU board.
Add the MQ-6 Gas Sensor (catalog type mq-6).
Connect VCC and GND to the supply and ground of the board. Use a supply inside the catalog range of 5 V.
Connect DOUT to a free GPIO pin.
Connect AOUT as your circuit needs.
Run the firmware. It reads the output of the part with the ADC of the MCU.
