Gas Detection system using wireless sensor network implemented in FPGA board

Hello. We are having a project about Gas Detection system using wireless sensor network implemented in FPGA board. Our concern is the FPGA board that we will be using. Does anyone here has an idea on what board is suited for our project.
Thank you.

hi,
i guess you need to clearly know what you want your FPGA to perform, how many sensor/data it handle and how you want your FPGA interface with all your sensor and how you want to process your data. All FPGA like Altera and Xilinx they do come with Soft processor so you can design standalone processing so it solely depend on how large your design is (how many gates) to choose which FPGA suits you. For starter, can check out their development kits and it can comes in handy.

our main goal is to develop a gas leak detection system implemented in FPGA board using wireless sensor network. The system particularly detects the presence of LPG gas leakage using MQ-6 gas sensor which is low cost and is suitable for diverse applications. The functionality of the proposed gas detection system involved two main parts: (1) detection and (2) alerting. For the detection, the sensor will detect LPG, propane, butane and methane wherein the MQ-6 possesses high sensitivity to the mentioned types of gases and also to natural gas. The output from the MQ-6 sensor will be fed to the GPIO pins of the FPGA board for the monitoring of gas concentration in the air.In a confined environment, the MQ-6 sensor will detect the gas leak and send it to the GPIO pins of the FPGA board. The FPGA will analyze the LPG gas sensor output and display the values to the LCD. If the LPG concentration > 10000ppm, the alarm buzzer will be turn on and the FPGA will send a Call to the specified number. thank you..

can someone help us, pls give us some tips and techniques about this project..thank you in advance.

I think you will probably interfacing with sensor and a gsm module which usually interface using uart and audio input/output. For the sensor, you might need to see if the sensor output is dc or ac voltage. If ac, you might consider an adc if you need accurate reading from the sensor.

For the fpga part, the most direct solution will be a soft processor like niosII or microblaze which provided by vendor and hook them up with controller such as uart and etc. it will just work like an microprocessor like arm, 8051, and pic. So, if you system only interface with few sensor, a low cost fpga like cyclone or spartan series fpga will do the job. Just make sure they have enough GPIO for your entire system. For starting, just use their development kits that have uart, audio in/out, enough GPIO (adc maybe optional) and enough amount of memory for storage will do. Don't forget to check out their soft processor reference design to help you started.

Seriously speaking, I don't see a technical reason to use a FPGA for the project unless you want to implement the RF part as "software radio". But this would be clearly beyond the scope of a beginners project.

The MQ-6 sensor has an analog output signal which can't be directly processed by a FPGA. You need an ADC to convert the signal to digital.

First of all, the output of the MQ-6 is a resistance; you will need some interface circuitry, you can't just connect it to GPIO, which is digital.

Now, what, exactly, is your question? Do you want me to design this for you? Basically, you've just stated a bunch of requirements.

thank you sir.. i don't know where should i start and the design process. thank you and godbless sir
