I designed projects like Off line UPS up to 3 KVA, synchronous rectifiers, Solar MPPT chargers, Battery chargers ,Grid tie inverters design with PLL and feedback control circuit emergency light of 66W and Online UPS control cards, Battery Charging power supplies, LED drivers for PWM controlling and dimming, SMPS, Power supplies. I have experience in schematics and PCB design experience in Altium and ORCAD. I am ready to work for you. Please contact for further discussion.

Thank you for the invitation. Its an interesting job and I am planning to do it using long range RF solution. There will be two kind of device. One to gather the sensor data and other one will be connected to your router. The RF module that I will be using will have range of around 1.1Km when clear line of sight is available, however I am sure that clear LOS is not present there and this will still manage to push the data to 110 meter comfortably. I will develop a crude testing prototype here (yes I have every parts ready at my stock so no problems) and send you ready solution. My bid includes PCB design as well. Please share some more details about type of power availability at those nodes where sensors will be placed. Lets discuss and get it done. Thanks

Hello there, I have built such system with MRI machine . Which city you are in ? Is it possible to discuss for a minute

C, C++, VB3, VB4, VB5, VB6, VB, VB.NET 2015, ASP.NET, MVC, WPF, XML, MSSQL 2014, HTML & CSS3, AWS(Amazon Web Service) programmer. I have experience about 20 years (32,000+ hours) in programming complex database application as well as Windows Desktop and Server/Client application. you will get yearly service and support as well as update of this software to avail new version from me. I am professional to provide corporate custom complex software which is not available in the recent market. So you may turn your desired application dream to real. Long term support. Electronics =========== I have experience on digital electronics for 15 years and analog electronics for 25 years.. (power, radio, tv, player, etc) Including microprocessor programming on assembly language (GSM to PSTN Gateway firmware + hardware) and desktop application with visual basic or vb.net to use UI... I can understand C++ and write also .. i have experience on Arduino UNO with AT Mega 328.. So if i get a chance to work with this project it will be a very challenging job for me to make the device perfect to work ...

Hello. There ar several variants to make it. You may use long-range WiFI device (ESP8266 with external anthenna). I've got a range near to 200 m, but there is a video where people use a good WiFi anthenna on the router and have 1.5 KM range (outdoor). Also, some other variants are also possible: rf module, wired connection or GSM. (I think, you have a GSM coverage and traffic can be really low, so that will not expencive in use) Also it's possible to use another ESP8266 WiFi device, placed somewhere in the midle, as retranslator. It may collect a data from senors (even several of them, if necessary) and send to your server. Also, It can work as simple web-server, so you may see your chart without any additional server (but there is some limitation, so it needs a discussion)

Can you tell me more , please

Hello, Deep is here from Ahmedabad, India. I can help you for your work. Let me know how do you want to send data to server using Wireless (WiFi / GPRS) or Ethernet? And How many sensor inputs are there? Sensor output analog or digital? Looking forward for your replay. Thanks

HI Thank you for inviting me for the project. Please share more details on the project. I believe we I have necesarry experince to develop sensor-cloud system. Looking forward to hear from you Thank you. Anusha

Hi, Thank you for the Bid invitation. I am an electrical engineer having an experience of four years in embedded and power electronics industries. I have design 48 channel temperature data logger for chemical industry. As you mentioned that distance may create the problem but we can solve that by putting RF transceiver on each node and Master RF will be connected to router via wifi. I have done similar job previously and it is working fine. I have been working on STM32 microcontroller since last 4 years and i am a good PCB designer and microcontroller programmer. Do let me know if you have any queries/questions. Let us at least get into the interview stage and discuss things. Hoping to hear from you, Jaydip Kathiriya

Hello Dear, We are a team of experts with a cumulative experience of more than 50 years in the field of embedded systems, electronics and prototype development.

Hi: ESP8266 can work for you. Mess-networking! This is cheapest, and has good range. What is the sensor model no.? Please feel free to write back if you consider. -Sam

Hi I would like to inform I am expert on IoT and cloud computing. I've done many similar project which you can see in my profile. Looking forward for more discussion about your project

FREELANCER RECOMMENDED ------------------------------------------------------ Can help... I am an Expert... Lets Start! Please start a Discussion with me and we can get started from there... Please check the past projects I have handled and check my reviews for what employers have to say about my work... Can start right now...

Dear client. I can work on this DAQ/ IoT type project. I am expert in embedded systems (3 years). I work full time as a freelancer. If you are satisfied with my skills and expertise, I am happy to discuss! Thank you Shamir

Hello. I'm an embedded systems designer with a specialty in embedded communications and protocols. I understand you need a wireless sensor network all reporting to a single base that may be (at worst) 115 m away them. I will employ 2.4GHz radios or sub-GHz radios that offer both range and penetration through the walls of your cold storage building. Each radio will be coupled to a cheap Arduino together with the sensor and RTC to make a compact unit. The base system will built around the extremely cheap yet reliable ESP8266 WiFi SoC which will poll the 5 sensor nodes to get their data as well as host the HTTP server to make all the data available on your LAN. I can execute your project efficiently. Contact me to discuss details; I look forward to working with you.

Hi, I am an Embedded system Engineer and works in a good firm as an embedded developer. I have made many projects from inception to real products using ESP8266 (blev4.0 and wifi) module. I have recently designed Wireless Tyre Pressure Monitoring system for an reputed IVS (Intelligent vehicle system) in hungry. By having this in your tyres it will tell the user about pressures and this is integrated with a online web portal using wifi module. Other than this i have used this Module in following Project. 1) Online Cold Chain Monitoring services for measuring temperature 2) Online Fuel Monitoring System I have excellent skills on wireless technologies as i have 5 years of industrial experience. I assure you that i will provide you with quality work and on time completion . Please contact me as soon as possible. . Looking forward to a positive response.
