Built IoT end points using ESP8266 or any other Low power WiFi chip with MTQQ architecture

Hi, I understand that the scope of the project consists of: - design of electronic circuit based on some sensors and a LP WiFi chipset (including PCB's gerber files and BoM) - design and implementation of firmware that will implementof MQTT layer on the sensor side - integration of the circuit with an MQTT broker (i.e. HiveMQ) that will run on LAMP (Linux/Apache/MySQL/PHP) server - the main restriction is that the board must be manufacturable for less than 500.000INR for 500 units, including costs of PCB manufacturing, components, mounting and soldering. Based on that information, the proposal's budget is based on an estimation of 25 working days over a minimum of 5 weeks elapsed time. The first 5 days should be dedicated to refine requirements (like how will the sensor will be attached/detached from the board, casing -if needed-, MQTT broker to be used, etc). I have split the project in three main phases: - Requirement refinement: 3 working days to refine requirements - PCB design (prototype and firmware included) - Integration tests The deliverable will include all the files that the manufacturer will need to build and mount the boards and the firmware to burn the MCU.

Hi, I hope you are doing well. I have experience with MQTT sensor network using ESP8266. I can execute this project in less possible time. Looking Forward, Khawaja

Hello I have got your job posting “Built IoT end points using ESP8266 or any other Low power WiFi chip with MTQQ architecture” and I am very much interested to work in your project. I am a circuit designer and have more than 5 years experience of working with the embedded systems(Arduino,Rasberry pi ,ARM processors ,PIC microcontrollers,Wireless boards,TFT Touch Displays,All types of sensors and actuators). i have done tons of similar projects So, I think you’ll find, I have the skills you’re looking for. For more on my skills and successfully finished projects, please have a look on my Profile and Portfolio. I have all the components available here with me so i will develop a working prototype according to your specifications and then send you the code and schematics so things will work for sure.I will remotely guide you and help you build the prototype on your side.I also offer unlimited revisions of the code and you get timely updates of the project. I am always available on Email and Skype. Please have a voice or video chat if necessary. I will be available more than 60 hours per week and able to start your project as soon as possible according to you. Thank you for your consideration, Best Regards, Haseeb Shafqat
