Arduino based SMS based Relay

hi sir i am an expert electrical engineer i can do it for you. i have read the details and i am very interested in your project please consider me for your task. i assure you quality work and on time delivery i am waiting for your reply regards

Hello! We have expirence in similar tasks. Please contact us to discuss details. Best regards, Oleksandr

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. I can help you with your deal and since im new one here I can do it cheaper then anybody. (autopromotion^)) Schematic is needed, but actual device is needed too for good debuging. Or prototype can be built using breadboard. And what do you mean with "either arduino, or some C code"? What hardware do you have? Give more info and lets talk.

Hello. I can do this work, for you. :) .

Hi, Have a great day. WE are startup R&D company. Our Bid is little higher than your budget, we will design a complete system and deliver the following. 1. Schematics. 2. Bill Of Material 3. Firmware. 4. Working Prototype. Please note we will design the system based on SIM900 and arduino. Please feel free to contact. Best Regards, Shahbaz.

Dear Sir, We have previous experiences with electronic system development using GSM, Bluetooth and WiFi communication. Please see our profile for past projects. following parts are included for above bid. 1. Device Firmware (Atmega328P Code on Arduino Platform) 2. Schematic development ( Eagle 6.4) 3. PCB design ( Eagle 6.4 ) 4. 1 prototype development 5. Instruction Sheet Please let us know any other specifications like size and dimensions as you required. Waiting to talk with you. Best regards, Lasantha Prasad

Hello Sir, I went through your project proposal and it's very interesting and I would like to work on this project. Why you should hire me ? * I have four year experience as a freelancer and I am very efficient. * I have many good feed backs. Please visit this link and see for yourself some of my feedbacks on freelancer.com https://www.freelancer.com/u/Anthony989.html * I can support you if you are willing to mass produce this as a product. I have many contacts in China. *I work full time as a freelancer and I will work as planned,on time. * I have very attractive milestone payment system that benefits both parties and ensure employer-employee trust. For your project I have completed most of them lately. I have experience in both SIM900/908. And I am very familiar with their AT commands. You can check my portfolio. I have uploaded a video of GSM network based RFID writer/reader. Please contact me if you are interested. I am keenly waiting

Hello. I carefully has studied your files and now I have fully understanding of what is necessary in that project. I already have made devices which uses both SIM900 and SIM 800. This devices uses SMS for sending of data and for control (start upload of data to FTP, hardware restart and so on). For authentification i had used phonenumbers, pre-saved to SIM-card. But, of course, it's possible to store them on EEPROM. Since the library for working with FTP at the time of the job did not exist, I wrote the code for these tasks "from scratch", without using of any GSM-library. I had to make considerable efforts to obtain an acceptable speed transmission of large amounts of data. These modules are slow, especially '900' version, so I had to optimize the work with module and study it well. Also i have experience of usage different types of LCD-displays. I think than display is usefull option for that device. Then you can display current temperature (even in kind of "analog" thermometer, for the better look ), set up timer and even to manage admin's phonenumbers and (if necessary) - passwords locally. I made some temperature-regulation devices (up to 2 KW) using i2C sensors and analog sensors, with both relay and PWM. Also i made alarm device for sending voice-messages with SIM900. This device capable to send short voice-messages , pre-saved to SD-card. Is possible to use MCU's built-in memory for that, without SD-card, but for very short messages. Have a good day Maxim

Hello, I have check the attachment and I am interested in this project. And I have experience doing such projects. I have the hardware for prototype as well. Wish to see the schematic done. Please do not hesitate to write back if you consider. Thank you. Sam

I'm an Electrical Engineer in Communications and Electronics. I have experience in microcontrollers programming, including PIC and AVR. Additionally I have worked with arduino and raspberry-pi boards and have designed many PIC-based boards for solving specific industry tasks. I hope I can help with this project Best regards

Hi, We are a team of engineers with more than 10 years of experience in designing and developing various digital and embedded systems... Currently, apart from our R&D, we help engineering students to complete their academic projects. Also conduct seminars and workshops on Microcontrollers and Robotics... So we have experienced with a lot of Microcontrollers such as PIC, AVR, ARM, Arduino etc. We are also experienced with a lot of sensors and sensor modules.... We are very proficient with PCB desingning tools such as EAGLE, KICAD etc... We have done a lot of projects with arduino, please check my completed projects and reviews given by other employers...:-) We really would like to know more about your project, kindly let me know if you are interested...:-) Thank You

Hi, Greetings! I am experienced and Qualified B. Sc Electrical Electronics Engineer with 5 years of experience in Embedded systems and Automation's (200 + Projects) .I have read your requirements and want to discuss more about the project , so I can start work immediately. For more you can view my portfolio by clicking https://www.freelancer.com/u/enggrsujad.html. I am just a click away. Have Good Day ahead. Regards Engr Sujad

I had build the arduino base SMS temperature monitoring unit with start of UPS and alarm to user if the temperature out of range, my previous project is very near to what you need there, so i am sure can get what you need. the set up on your document is SMS base, but it would also be nice to have LCD/button shield on the arduino to have some on site monitoring. which i had experience with my previous client about this work. Please let me help you with this project and I am sure can get you very good product. ( quote included all hardware build ready for ship, not included shipping)

Dear Employer, I have read your project description and can assure you that I can do this assignment. I have a years of experience with arduino boards and also with AtMega328 controllers for application development in C. I have experience with development of home appliances power monitoring and control nodes and have also worked with GSM modules. I am confident to say that I can provide you with robust and bug free firmware for your hardware. Best Regards, SharpSense Research Engineer & Freelance Electronics Design Engineer

Experience in GSM/GPRS communication with Gumstix, Beaglebone and SIM300 module. Have done two projects on the same. Commands can be sent to the microcontroller via SMS which performs acts like turning ON/OFF of Equipments ( Inverter in our case ). Can deliver the project in committed time with at most satisfaction. Thanks

its easy to interface GSM with arduino, but your config is too long, so i needs time to create these instruction as your attachments i prefer to use GSM 900, i ll supply you the code and schismatic in addition to relay driver for 20000 watt load with arduino and gsm
