DIYmalls 8pcs Load Cell 50kg Weight Sensor Half Bridge Strain Gauge Human Body Digital Scale + 2pcs HX711 Amplifier AD Module for Arduino
Load cell is an instrument that helps to determine size of a load (either a force or weight) and converts mechanical force into digital output. It consists of a metal core and a set of electrical resistances that transform when a force is applied to it. But it returns to its original state after force removed. It have many purposes, including telling weight of something, weight change over time and measure strain and load on a surface. It's perfect for electronic scales, digital scales, electronic balance and many commercial scales weight involved. To use a load cell, you need first calibrate it where you can increase or decrease calibration factor units to get your correct weight using a microcontroller. Frequently Asked Question Q:What is the range of output? how low will it accurately go? i need accuracy to at least 200g, preferably lower A:The accuracy depends mostly on the ADC resolution, 24Bit in the case of standard HX711, accuracy will be better than 200g even with 50KG load cell, it will be in the order of few grams at most Q: How accurate can I measure items? If I use more than one cell does the accuracy improve or degrade? A: this type of cell, which is 50kg half bridge will provide a typical accuracy of 50 to 100g with a maximum range of 200K for 4 cells. Adding more cells will increase the maximum load and decrease accuracy.
