Introduction

Weight Sensor Module is based on HX711,which is a precision 24-bit analog-to-digital convertor designed for weigh scale and industrial control applications to interface directly with a bridge sensor.Compared with other chips, HX711 not only has a few basic function,also contains high integration,fast response,immunity,and other features.The chip lowedrs the cost of the electronic scale,at the same time,improving the performance and reliability. The input interface of this weight sensor module is used sensor interface,which is compatible with Arduino I/O port.The output adopts compact terminal that makes weight sensor module easier to connect the weight sensor.It's the best choose for electronic enthusiast to do some tiny home scale.

The weight sensor module can be combined with weight sensor on the market. We also help you to pick a small range of weight sensor.

Tutorial

The range of the weight scale is only 1kg. So, it's very appropriate for you to make a kitchen scale.we will bring you a step by step tutorial to make one and print the data by Arduino Serial Monitor.

Hardware Requirement
1x DFRduino UNO R3 1x Weight Sensor Module 1x IO Expansion Shield for Arduino V7.1
1x Weighing platform Reference 3D model Note:The weighing platform will be made by yourself according to the weight sensor machine drawing.The following figure show the weight sensor machine drawing.

Software Requirement
• Arduino IDE
• Hx711 library

Detail Steps

Install the Arduino library to your Arduino IDE. Open the sample code ,which is named SerialScale.ino.
sample code Upload the sample code to UNO. When finished, you put the weight sensor horizontally, one end with four wires is fixed on the table, the other one suspended.
place the sensor

Open the Serial press the sensor according to the label direction. label direction press the sensor

Check the Serial monitor, when you press the sensor Left image Normal data.The date will have a growth process with different intensity of hand. Right image:Abnormal data. Possible Reasons a. Forced direction is wrong. b. Maybe the connection isn't firm.

Thus, far ,the weight scale will be finished within one more step-- zero adjustment. Open the Hx711 library folder , and find the file Hx711.h, open it. Locate the statement void setScale float scale = 1992.f You only need to adjust the number 1992 to find the appropriate value for weight scale. Save the h file, and upload the above code again.
