Need Data Logger circuit - Log Current, Voltage & Temp

Hi, my propposed circuit will be based on Arduino, we can use Arduino nano , Uno, or even mega, it's depend on you. my suggestion Nano is enough . for voltage reader, I will use simple resistor divider and zener to avoid over voltage, and connect it to Arduino ADC. For Current reader, I propposed to use Ina219 current reader module, it's SPI / I2C based interface , I'm forgot about it. for temperature, we can looking for available temperature sensor on the market. and for log data, we can use SD Card, I guess it's SPI based interface. let me know your response. this is fairly simple project that could be done in 1-2 day. I have did something like this since 2012. I will use Eagle for pcb design software, and 2 layer is enough. Best Regards, Rijal

Hello, I can help you with your data Logger project using an Arduino platform, but. I need more information about your project, current components, deadline, budget, and other things. Deliverable items: - Code Arduino well explained and commented. - Wiring Arduino diagram. If you have any questions feel free to ask and contact me before your order. Thank you and Have a good day, John.

Hi and good morning, while is self evident that you can count upon lower bids also consider what you're actually buying: some more dollars won't make a difference, a well done project will. If you think can be useful we can discuss details like: Do you need a display ? Do you need protection for excessive current/voltage ? What is the resolution & precision you need ? Do you want to connect a PC in real-time ? Once they're clear I can make a meaningful bid. All the best, Alex.

Hello sir i am an Electrical engineer as well as a product designer and have work experience in my fields. !!! i can do that within 2 hours from now!!!

hello I'm a Mechatronics Engineer who is experienced with embedded systems and automation. I achieved successfully prototype for data logging system for smart irrigation system. Furthermore, I have good knowledge in building SCADA system I would be a pleasure to work with you.

Greetings! 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 Hardeep Kaur

Hi! I have read your project and I am 100% sure I can complete your project. Because I have already designed this product and use it for my testing using arduino controller.\ Please contact me and I will make the alterations as per your demands.

Hello It is relatively simple project. Since you don't have any restrictions on the parts, it will be easier to work on this. The only question is where you want to store the data? Regards

hello, I can design what you want it will be based on arduino, for : - voltage : it will be using voltage divider - current sensor : using ACS712 with 20A max - temperature sensor : lm35 but its measure only on -55 ºC to +150 ºC and all data log will be save in sdcard, which you can copy it

Dear Sir, I have read the project carefully. Yet I am not clear. I need to know more details. I think you want to use this as a multi meter. And put the data into an Excel file. I want to do the task using Arduino and have some experiences to do the project according to your needs. I will be glad if you contact with me. Please send me a message and we discuss about the project and submission time. Thankfully, Md. Mubin
