PC and Analog MQ-8 Hydrogen Gas Sensor based Wireless Hydrogen Gas Monitoring System with ATmega16 and LCD Display using Series 2 Zig Bee
In this project, we will learn about PC and Analog MQ-8 Hydrogen Gas Sensor based Wireless Hydrogen Gas Monitoring System with AVR ATmega16 Microcontroller and LCD Display using Series 2 Zig Bee. Here, we will display and monitor the concentration of Hydrogen Gas wirelessly from a PC/Laptop using Zig Bee and 16X2 Alphanumeric LCD.
Since, the output of the Analog MQ-8 Hydrogen 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-8 Hydrogen Gas Sensor to the Zig Bee through USART communication protocol. This Zig Bee transmits the digital value of Analog MQ-8 Hydrogen Gas Sensor wirelessly to another Zig Bee connected with the PC/Laptop. At the PC/Laptop end, Zig Bee receives the digital value of Analog MQ-8 Hydrogen Gas Sensor and transmits that to the PC/Laptop through a USB cable. In the PC, the RealTerm Software receives the digital value of Analog MQ-8 Hydrogen Gas Sensor and displays it. Apart from PC/Laptop, microcontroller will display the Analog MQ-8 Hydrogen Gas Sensor value in 16X2 Alphanumeric LCD. In this way, the concentration of Hydrogen Gas is monitored from the PC/Laptop wirelessly and from alphanumeric LCD.
Now, we will use some source of Hydrogen Gas near Analog MQ-8 Hydrogen Gas Sensor and we will see the change in concentration of Hydrogen Gas in PC and Alphanumeric LCD.
