MQ135 - on Raspberry Pi - Raspberry Pi Forums

· So i am trying to build a sensor mainly for C02 using a mq135 sensor with Raspberry-Pi. I've seen some examples but they don't seem to be working for me. So far I've connected the VCC from the sensor to 5v GPIO pin and GND to the GND. I've also hooked the AO to the breadboard so that it is attached to the MCP3008 converter.
