Load Cell Sensors are transducers (transducers, electronic components that can measure physical quantities into electrical signals) that can convert the pressure by the load into an electrical signal. IC HX711 is a weighing module, which has a working principle of converting the measured changes in resistance changes and converting them into voltage quantities through the existing circuit. Load cell and HX7411 are used to obtain data of weight which will be compared with a commercial digital weight scale that the accuracy has been verified. In collecting data of weight, there are several calculation methods including the mean, modus, and median method. This study aims to provide test results for the three methods with different variations in delay. Delay is used to avoid errors in taking data from the sensor directly and also to provide pauses for the sensor in real time data collection. The test was conducted with four human subjects who have differences in body weight. The variation of delay used is 250ms, 500ms, 750ms, and 1000ms. The test results show that when testing variations in body weight with a delay time of 250ms, the mean method has the best results with a value of nmean = 2. In the 500ms delay test, the median method has the best results with the value nmedian = 3. In the 500ms delay test, the mean and median methods have the same good results with values of nmean = 2 and nmedian = 2. In the 1000ms delay test, the median method has the best results with a value of nmedian = 2. The results of the whole test show that the values of Nmean = 6, Nmedian = 8, and Nmodus = 2 which indicate that the median method is the method that has the best level of precision.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
