How much does the Load Cell cost and where can I find one?

Cost of load cell depends on its capacity to measure weights.A 1Kg load cell costs around 200₹

What I do not understand,you (the one you copied the code) defined a constant"calibration_factor" and equals it to the factor from calibration code I missed in your post. Further down in the code where you need that factor you do not use the defined constant by name, but you enter the fact again in numbers. So thats frustrating for anyone who does not go deep in the code and enters the factor where the constant is defined but nothing changes in the output of the scale. So you should better use the named constant down in the code, would be more user friendly to enter the factor on top where the constant is defined, instead haveing to search the code to find where to enter the factor Rainer

Hey I can't understand what you think about the code. I calibrated for my 3kg load cell and I put it on scale factor which was got by using the calibration factor of 96650. If anything let me know

I found this on amazon - its cheaper from chineese suppliers - make sure you get the board also https://www.amazon.com/Geekstory-Weight-Electronic-Kitchen-Weighing/dp/B079FQNJJH/ref=sr_1_1_sspa/144-5279827-6023550?ie=UTF8&qid=1538310041&sr=8-1-spons&keywords=3kg+load+cell&psc=1

You gan get a load cell from AMAZON or Quartz components .com for a relatively low price.

Can anyone tell me a software where I can simulate the entire project?

isn't that a software to just upload the program to the arduino board? I want to create a virtual simulation of the entire project using software like tinkercad. But the hx711 module is not available in tinkercad. so if someone can suggest an alternative software?

I think that you should download the latest Arduino IDE software from Arduino .cc
