Digital sensors and the Raspberry Pi with the smoke ...

The MQx series of smoke detectors work well with Arduino and Raspberry Pi. This sensor, the MQ7 FC22, has analog and digital , we’ll use the digital output pin labeled d0 on the sensor to output a warning if CO(, smoke) is detected. Alternatively, the analog output could be used to measure the level of CO, but this will need an analog/digital converter like MCP3008.
