4PCS Load Cell 50kg Weight Sensor Half Bridge Strain Gauge Body Scale for Arduino

Description：
This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales (you know, the ones you use in January for your New Year’s resolutions, and then forget about a month later).

The sensor is a group of half-bridge strain gauge, there are 3 ways to use it :
1. Use one sensor with an external resistor to form a full-bridge measurement, the range of a sensor range: 50kg. External resistance on the higher requirements.

2.Use two sensors to form a full-bridge measurement, measuring range for the sum of the two sensors: 50kgx2 = 100kg

3.Use four sensors to form a full-bridge measurement, measuring range for the sum of four sensors: 50kgx4 = 200kg

Package Includes:
1 X Human Scale Load Cell 50kg

FAQ

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.
