Also connect from the Raspberry Pi (LV) and 5V (HV) to the TTL. And also 5V to the VCC pin of the gas sensor and GND from the Raspberry Pi comes to GND on the LV and HV side of the TTL, as well as to GND of the MQ2. Schematically the whole looks as follows: I use the 5V of the Raspberry Pi’s.
In this instructable you will learn how to build an IoT gas detector using an Arduino, a Raspberry Pi, and an MQ-5 gas sensor. In addition to these parts you will need three wires to connect the Arduino to the gas sensor. Once that's done you will be able to write code for the Arduino and Raspberry Pi to get the current gas level in the room, be it natural gas, alcohol, or even your breath ...
