Schematics

Circuit connections

The BOLT IOT MODULE has 5 GPIO pins from 0 to 4 and 1 analog pin A0 . The GND of the BOLT IOT is connected to the BREAD BOARD to which the GND of the GAS SENSOR is further connected. Similarly the VCC and A0 pin are connected together. Now for the buzzer the positive terminal is connected to the GPIO pin 1 and negative terminal to the GND of the BREAD BOARD.
