Hello Sir! I really like your project and not only because of the financial aspect but because of the device to be designed. I've been working with ESP32 as IC and as a part of a module like the ESP32-WROOM-32E, you've mentioned in your description. I'm familiar with most of negative sides of the ESP32, what I can explain in details if needed. 1) Project milestone: I can make all the drawings necessary for PCB manufacturing within 2 weeks. The software development depends a bit on the prototypes available for testing. 2) Payment: I'm completely agreed to receive a certain percentage on gross profit and no milestones required, so you don't have to spend your money on development stage on me and I'll be more then interested to design a well working device to got paid. I don't want to describe any technical details in my offer, I will do that if you are interested to work with me on this project. Regarding the NDA, I have nothing against, feel free to send it me and I will sign it. What I will deliver: 1) The complete hardware drawings and documentation, ready for manufacturing. 2) Software sources. 3) Software binaries of the compiled sources, ready for programming. Thank you for reading my proposal, I'll be glad to provide you more ideas about this project via chat.

I have 3 years experience in Iot and embedded systems and have good hands on both hardware and software. I have worked on many projects that are as follows: Smart lock based on esp8266 Smart water management system based on esp8266 and AWS server Smart energy meter solution Smart curtain controller all the above are based on esp8266 and AWS server i have also worked on electric vehicle and implemented internet of things concept there too. I have read your custom ultrasonic sensors requirement. but one thing is that it will take time i cannot assure you that it will be completed by october, it will be completed by the end of the year. we just need your patience and my hardwork. looking forward to work with you regards Prashant Mishra

Hi there, I am an electronic engineer with rich experience. Yes I can provide the schematic, coding and PCB design for this project. I have planned to use ESP8266 as a controller and will use SMD components in PCB for professional look and proper signal and power transmission. Tx and Rx part can be done by using Firebase. Contact me for further discussion. Thanks

How are you? My quotes is final 700 for 25days. For detailed time line and milestones, i 'd like to discuss with you kindly. Love to hear from you. Thank you. Anton.

Altium experienced in PCB designing from past 10 years and has designed and written codes/program for various projects. PCB designed for various microcontrollers, microprocessors, FPGA and ASOCs. I have few questions about this project: 1. I acknowledge that the project includes developing hardware and writting firmwares as well, but Do you need the first prototype to be produced? 2. Do you need on-board programming facility for ESP32? 3. I assume you are using HC-SR04 ultrasonic sensor, can you please confirm this? 4. By quad 7 segment display, you mean 4-digit 7segment display. please confirm 5. Is it ok for you if the firmware is written in Arduino IDE? Proposed Milestones: 1. Development of schematics according to your requirement. (After the schematic is complete, it will be sent to you to verify about your requirements) 2. Development of PCB layout and board designs. 3. writing of firmwares. if you opt for prototype production: 4. Getting PCB fabricated 5. procuring the components. 6. Assembly and cold testing. 7. troubleshooting if any. Although I was working as freelancer for local Industries, I am quite new to this website so I haven't managed to gather any reviews yet. I expect your kind consideration about this matter. Lead time and quote can be mutually discussed in chat or on mail. hoping to hear from you.
