Electronic Balance Weighing Load Cell Sensor 5Kg with HX711 Module


Electronic Balance Weighing Load Cell Sensor 5Kg with HX711 Module

This straight bar load cell (also called a strain gauge) can translate up to 5kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar. With this gauge you will be able to tell just how heavy an object is, if an object’s weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.

This straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 5kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows: red = E+, green = O+, black = E-, and white = O-. Additionally, these load cells offer an IP66 protection rating and feature two M4 and two M5 sized thru holes for mounting purposes.

Overview HX711 Module
HX711 is an electronic scale module, whose working principle is to convert the measured changes in resistance value changes, through the conversion circuit into electrical output. The module communicates with the host computer through TTL 232.

Simple structure, easy to use, stable and reliable performance, high sensitivity and measurement speed and so on.

Widely used in aerospace, mechanical, electrical, chemical, construction, medicine and many other fields, used to measure force, pressure, displacement, strain, torque, acceleration.

Differential input voltage: ±40mV(Full-scale differential input voltage is ± 40mV)
Data accuracy: 24 bit (24 bit A / D converter chip.)
Refresh frequency: 80 Hz
Operating Voltage : 5V DC
Operating current : <10 mA
