In this project, we will learn Analog MQ-5 LPG Gas Sensor Interfacing with AVR ATmega16 Microcontroller and LED Display. Here, we will interface an Analog MQ-5 LPG Gas Sensor with ATmega16 microcontroller and we will display the Analog MQ-5 LPG Gas Sensor value in the 1X8 LED array.

Since, the output of the Analog MQ-5 LPG Gas Sensor is analog in nature and these analog signals cannot be processed directly by the ATmega16 microcontroller. So, first this signal needs to be converted to digital value to be processed by the microcontroller. The conversion can be done with the help of ADC of the AVR ATmega16 microcontroller. After converting the analog signal to digital, the microcontroller will display the digital value of Analog MQ-5 LPG Gas Sensor in the 1×8 LED array. But the LED array can display only 8-bit at a time. So, the 1×8 LED array will first display the lower 8-bit and then the upper 2-bit of the 10-bit digital output with a delay of 500ms.

Now, we will use a lighter as a LPG gas source near Analog MQ-5 LPG Gas Sensor and we will see the changes in the output of Analog MQ-5 LPG Gas Sensor in the LED array.
