A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. The primary benefit of the circuit is its ability to provide extremely accurate measurements (in contrast with something like a simple voltage divider). Its operation is similar to the original potentiometer.

The Wheatstone bridge was invented by Samuel Hunter Christie (sometimes spelled //"Christy"//) in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. One of the Wheatstone bridge's initial uses was for soil analysis and comparison.

==== YR-3180 Intelligent weighting sensor module ====
{{anchor:yr_3180}}
The weighing acquisition module is a high-performance, multi-functional electronic weighing equipment. It adopts advanced weighing sensing technology and can measure the weight of items in real time and display it with a five-digit digital tube. It also has upper and lower limit alarm functions. capable of achieving precise weighing control and monitoring. At the same time, this product also has TTL communication interface and [[com:basic_modbus|Modbus RTU]] communication protocol, which can communicate with PLC, computers and other equipment conveniently and quickly to realize the transmission and remote control of weighing data. In addition, it also supports Type-C power supply and button debugging functions, improving the convenience and stability of use.
