I2Q MQ-4 Methane/Natural Gas Sensor Mini Module to Raspberry Pi

Can this sensor and ADC121C021 be directly connected to a Raspberry Pi via I2C without use of the “Master” controller unit? If so, what other electrical components (eg, pull-up resistors) are needed, and are the appropriate linux libraries available? thx

Hello @jax200 and welcome to the RobotShop forum,

Yes, you can connect it directly to the Raspberry Pi via I2C, and you don’t need additional components as the module comes with 4.7K Pull-Up jumpers.

You can find the libraries here:
