The development of microcontroller technology that is rapidly making applications to be developed as a work in the field of technology that can help and facilitate human activities. Researchers see that current technological developments there are many uses of loadcell sensors to detect weight on objects. The number of factors that affect the weight difference between digital scales and scales very significant conventional. Therefore researchers analyzed the use of loadcell sensors for calculate solid and liquid objects and analyze the work system and the accuracy of the accuracy on the loadcell sensor in calculating the weight of solid objects and liquid objects.

Abstract The more developed human needs about technology, the more research will be conducted on increasingly rapid technological developments, one example is IoT or Internet of things. It cannot be denied that IoT is a future technology that will be widely used by humans, because IoT has a concept that aims to expand the benefits of internet connectivity that is continuously connected. Allows humans to easily communicate with all equipment connected to the internet network. For this reason, the researcher developed a research on the concept of data communication between devices and interfaces. In this study the website uses wireless which is connected to the internet network. This wireless device will use the ESP8266 wireless module that has been embedded in the Wemos D1 R1 Mini.
