IOT project with wifi

Hi, This is fairly simple project that can be finished using only ESP8266 NodeMCU board. for cloud we can use cheap free platform like thingspeak, All resources available for accelerate development process. I can finish this project in 1-2 days, If there is no other sensor needed to buy(because there will be a delivery time). I have use Arduino since 2013 and had a structured workflow when it comes to arduino based project. Generally I'm professional Firmware engineer so, I will not dependend on arduino library, if there is no arduino library available, I can use direct register programming for device we will use. Lets discuss the detail over messenger, And Lets get started. Best Regards, Rijal

Hi, I hope you are doing well. I have expertise in embedded system design and development. I have expertise in IoT projects. I have understood your project requirements and I can execute it in less possible time. Looking Forward, Khawaja

I have build same project to build IoT device to send sensors data to the web server by using ESP8266 wifi module and Arduino MEGA. Have more than 15 years of experience on Digital Electronics.

If you are open to suggestions then i would suggest using esp8266 instead of the arduino platform, the deepsleep capabilities and the overall footprint of it better than arduino and also comes with built it wifi and hence wont need any thing extra, feel free to check my profile for past projects and reviews and think about using the esp to esp to update to the cloud and go to deepsleep and wait for input.

First, depend on the specific requirement, the cost vary significantly. I'd worked on a project that run on a Panasonic 18650 Li-ion for years with daily wake up and use ESP12F chip. To keep the cost minimum, the following assumptions are made: - Wake up signal is a digital input. - On wake up, the ESP12F will just read an ADC value and submit to cloud (using Rest API). Scope: 1. Design the schematic for ESP12F. 2. Write code for ESP to be deep sleep and wakeup. No state management is kept (i.e. wakeup by reset). 3. Write a simple nodejs backend to provide API for the ESP12F to call. Data is stored in MongoDB (mySQL is possible). No board nor shipment is included in this quote. Addition cost is required if you want to make prototype and shipment. Thanks!

I have more than 5 years experience in embedded systems and PCB design. so I can do your job within a time limit with your satisfaction.

i will work with nodemcu to do it so it will be wifi and arduino in same time to prevent power lose with deep sleep mode and wake up mode in same time

Hi. I work as Hardware Engineer in a company that develop IOT projects. My responsibilities in the enterprise are: Design the electronic circuits (analog, digital, control and power); Develop the code for the MCU and embedded systems using software like MPLAB X IDE, Arduino IDE and Python; Test and simulate the schematic of the circuit through simulation software (Proteus and MATLAB/Simulink).I have made projects relationated with the home automation using the internet of things using Wi-Fi and Bluetooth modules (ESP8266 and ESP32) and TCP/IP protocol mostly, but also using UART, I2C, SPI and 1 WIRE to communicate MCU with sensor, mostly current sensors and humidity and temperature sensor (DHT22). Also, the implementation of PIC12F, PIC16F, PIC18F, PIC24F and PIC32F, to make create sub circuits to measure data from sensors, creating small devices inside if the embedded system, like the design of a digital wattmeter with I2C communication with the master (ESP12F) using the PIC16F877A, Current and Voltage transformers. All of these projects are posted on my profile. Hope that I have fulfilled your expectations and can be a good candidate to work for your project. Hope we can dis

hello, I'm interested in this work, I can do it in 3 days max, so, if you want to work with me I will guarantee you a good job delivered in the good deadline thank you and good luck ^^

I hold master degree in instrument tech and having about 35 years of expertise in real time embedded hardware and software applications. I am specializing in IOT and well versed with Wi-Fi

Greetings! I can use the thingspeak to store and visualization of data. Please gone through thingspeak if you like it then please let me know. Otherwise I can save data on cloud too. Well, I am an electronic engineer and having 3+ years of experience of working as embedded engineer. I am well versed in Arduino Ide programming, sensor integration, raspberry pi all models, python, embedded c, processing ide. I have Experience of Working on all models of arduino. I've build self balancing robo with remote control, tricopter, 3d printer, finger print sensor based bike automation etc. As I am new on freelancer so I would request you with all my kind heart please give me a chance I would provide you best service. Money is not my concern I need to make a good profile because I am new on freelancer. It will be sincerely pleasure to hear back you soon. I am waiting for your positive response. Thank you so much. Best Regards Saurabh

we are a team of mechatronics engineer and have a great experience with Arduino, esp8266 wifi modules, and IOT based projects and have previously done many projects on the same as you require. we can also provide you with video demonstration to show the working of code. if interested please let me know and we can talk over chat or email to discuss the project. regards Puneet Paul

I have made projects like this and have prior experience in the modules which are to be used in the projects. I will complete this project on time as said. So please provide us with this project.

Hello ! My names is Timmy. Last year I'm IOT engineer of IOT company in Vietnam. I can help you code esp8266 to get data from Firebase, then, when firebase changed, your esp will do something you want. Please give me a chance to help you! Best Regards, Timmy Duong !

I have the hardware (esp8266) so i can test this code without bothering you. So development will be faster and robust. For good sleep mode i need to learn what hardware you are using. Some have nice hardware hacks for better sleep modes with less usage of watt but you may need to solder them. Can you solder?

Dear, We are a Argentinian company that have more than 7 years of experience in embedded programming, PCB's design with KiCad and industrial electronic systems implementation. And we have alliances with local and overseas partners for mass production. We can make the PCB and schematic design using KiKad and PCB assembly (We have SMT and soldering lines for small quantities prototype productions). We have a lot of experience in low power applications, cellphone chargers, battery chargers, motor control, H bridges (1 and 3 phases), etc. We can develop the complete solution, mechanical design and drawings, PCB design, PCB assembly, firmware programming, and machine assembly. This Bid proposal is only for PCB (schematics, PCB layout, and Gerbers). Programming, KiCad is an open source software suite for Electronic Design Automation (EDA). The programs handle Schematic Capture, and PCB Layout with Gerber output. The suite runs on Windows, Linux and macOS and is licensed under GNU GPL v3. Thanks you Leonel Caraccioli OpenMolo

Hello, I have 3 years of experience in internet of things. I am able to control appliances via internet using cloud or Bluetooth. Also able to work on raspberry Pi, Arduino, esp and other hardware programming. kindly share more details to proceed further. thanks

Hi there! I am an embedded software engineer at Sony. I have been designing, developing and delivering hardware and software for their Connected Technology Team for over 7 years as a senior developer. I am new to Freelancer and was encouraged by peers to try it out. Your project is exactly what I do professionally so I thought i could offer you a competitive price m in exchange for the experience of trying out Freelancer. I broad and robust skill set developing wireless networks, technology and electronic subsystems. If you are interested or would like to discuss further I would love to hear from you. Kind Regards Oskar

I've Recently Worked on IOT project. I have all the knowledge of this kind of work. I will make this project in 7 days. The components will be provided by you. Profile will be provided if you want. Thanks.
