Gas sensor embedded system

Before awarding to anyone, give me a chance to discuss it with you. I am embedded system electronics engineer with 3 years of experience in iot development. I have expertise in development board Arduino, ESP8266, Raspberry Pi, etc and the microcontroller ARM, Microchip, stm32f, etc and have worked on gas sensors. I can design and develop PCB. I have hands on experience in mobile app development that communicates with electronic hardware. I have worked on home automation, beacon based indoor positioning system, smart parking system with real parking spots update on mobile app, etc. Another iot product I worked on was women saftety device, on which, if women press the button, her location is shared with her family members and it starts recording audio to a cloud server automatically, while at the same time it calls nearest police station automatically. Please consider sending me a message so that we can discuss this further

Dear Sir, I am an electrical engineer with 19 years experience in this area , listed among top talented freelancers here. I am going through your requirements and will have some question. I am interested in your project , Gas sensor embedded system Please send me a private chat message.

hi about pcb wifi gas sensor: -will create custom pcb board based on esp8266 - pcb software : - will be 2 buttons ( reset , config button) - config button will run pcb board as access point so you can connect it via any web browser and set your full config : - AP (ssid,pass) - wifi (ssid,pass) - mqtt( broker , port,usr,pass) - upload ssl file if you need it secure) - pcb design + software will cost ( 1200 $) - mobile app with graph will cost ( 500 $) note: if you need we can send you a video of similar device pcb + full config page

Hello! If you are planning mass production, I think it makes sense to develop a printed circuit board for this device. If this is a single product, you can use the boards on the market. In any case, at the first stage, I suggest carefully analyzing the technical requirements of choosing the appropriate technical solution (in particular: WIFI, BLE or other types of communication).

Hello! I am very interested in your post project. i have rich experience on it. I think this project is very suitable for me and i am sure i can give you good result . I can help you if you'd like looking forward to work with you. thanks regards

Hello, What type of gases would you need to detect? there are a few gas sensors comply with arduino controller. they are MQ-1, MQ-2, to MQ-5. but they are for specific gases. Let know your target

Hello, My name is Andrei, i am a Romanian IOT Developer with a lot of experience in IOT projects and automatics . I have read the specs of the sensors , i know them , i already have it on my workshop. I have full deployed solutions with WiFi communications for EU region . Let's talk more about the project , i can even come to Paris for the implementation of the project. I can work with all types of Microcontroles programming in C , C++ , Mikro C , CCS C , Atmel Studio , Arduino , gcc . Creating Schematics and PCB in Kicad , Eagle , EasyEDA and Proteus (+simulation). i have an workshop full of parts and the infrastructure to build PCB and test the solution end to end using special tools (Spectrum analyzers , oscilloscope , logic analyzers ) Derivable on the project : Wiring diagram for prof of concept . Schematic design PCB Design Gerber files for manufacturing MCU code explained every line . As an additional service i can make you a full working prototype and ship to you. Regards, Andrei

i have already made IOT based gas sensor system using co2 , co, NH2, O, so i can do your job within a time limit with your satisfaction. and if you want to see a demo than i will saw you .

Hello, I would like to help with your project, bringing the required skills and experience. I believe to be highly competent in sensory, analog, RF, digital and power electronics design as well as embedded firmware for many microcontrollers. I have followed products from initial concept and prototyping to mass production. Some recent accomplishments are listed under my portfolio. For the Android app I am ready to outsource and manage its development, so that for you I will be a one-stop shop. Consider my bid as placeholder, to be adjusted depending e.g. on deliverables. I would welcome an initial contact via Freelancer chat to further discuss project and timeline. Thank you for the opportunity, Best Regards -v8volante PS je parle francais sans problemes.

Hi, Have worked on gas sensors based projects and also having experience of several wireless communication methods for the same. I have understood basic requirements of your project. Looking forward for your response to discuss further on project. Regards Akram
