Android Mobile and Analog MQ-6 LPG & LNG Gas Sensor based Wireless LPG & LNG Gas Monitoring System with ATmega16 and LCD Display using HC-05 Bluetooth
In this project, we will learn about Android Mobile and Analog MQ-6 LPG & LNG Gas Sensor based Wireless LPG & LNG Gas Monitoring System with AVR ATmega16 Microcontroller and LCD Display using HC-05 Bluetooth. Here, we will display and monitor the concentration of LPG & LNG Gas wirelessly from an Android Mobile using Bluetooth and 16X2 Alphanumeric LCD.
Since, the output of the Analog MQ-6 LPG & LNG 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 send the digital value of Analog MQ-6 LPG & LNG Gas Sensor to the HC-05 bluetooth through USART communication protocol. This HC-05 bluetooth transmits the digital value of Analog MQ-6 LPG & LNG Gas Sensor wirelessly to the bluetooth of the Android Mobile. The bluetooth of the Android Mobile receives the digital value of Analog MQ-6 LPG & LNG Gas Sensor through an Android App called Bluetooth Terminal and displays it. Apart from Andoid Mobile, microcontroller will display the Analog MQ-6 LPG & LNG Gas Sensor value in 16X2 Alphanumeric LCD. In this way, the concentration of LPG & LNG Gas is monitored from the Andoid Mobile wirelessly and from alphanumeric LCD.
Now, we will use any LPG or LNG Gas source near Analog MQ-6 LPG & LNG Gas Sensor and we will see the change in concentration of LPG & LNG Gas in Andoid Mobile and Alphanumeric LCD.
