This is a simple “Arduino Weight Measurement project”. Loquendo tts 7 patch exe download. Electronic weighing machine uses load cell to measure the weight produced by the load, here most load cells are follows the method of strain gauge, Which converts the pressure (force) into an electrical signal, these load cells have four strain gauges that are hooked up in a Wheatstone bridge formation. Components Required: For designing Arduino Weighing Machine using Load Cell & HX711 Module we use the following components. Each and every components are described below further. Arduino UNO Board 2.

This chip is designed for high-precision electronic scale and design, has two analog input. How to Upload Program or Code Into Arduino Pro Mini by Using CH340 UART Serial Converter. Arduino Uno Board and USB. HX711 Balance Sensor. Load Cell (can be any weight of load cell ie 20KG, 60KG or 100KG). Also the ADC on the arduino is 10 bit which provides a maximum of 2^10 ie. 1024 readings compared to HX711 which is 24 bit ADC and easy to interface. HX711 Datasheet. The Hx711 uses SPI interface to communiacate to the Arduino. (Refer Data sheet for more info) More info on DfRobots. Connecting to Arduino. Connection is pretty simple.
Connecting Wires 8. Mounting surface for Load Cell (Nuts, Bolts, Frame, Base) 9. Standard Weight blocks (100 gm) Components Description What is Load Cell? A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. It is basically a device that measures strain and then converts force into electric energy which serves as measurement for scientists and workers. The strain measurement by load cells helps in maintaining integrity of the unit under pressure and protects people and equipment nearby. HX711 Load Cell Amplifier The Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight.
By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. The HX711 uses a two-wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work, and numerous libraries have been written, making it easy to read data from the HX711. Check the hookup guide below for more information. Load cells use a four-wire Wheatstone bridge configuration to connect to the HX711. These are commonly colored RED, BLK, WHT, GRN and YLW.
Each color corresponds to the conventional color coding of load cells: Red (Excitation+ or VCC) Black (Excitation- or GND) White (Amplifier+, Signal+ or Output+) Green (A-, S- or O-) Yellow (Shield) Arduino Weighing Machine using Load Cell HX711 Module Load Cell & HX711 Connection: - RED Wire is connected to E+ - BLACK Wire is connected to E- - WHITE Wire is connected to A- - GREEN Wire is connected to A+ Load Cell Assembly on Base: A base is also required to fix the load cell over it by using nuts and bolts. Here we have used a hard plyboard for the frame for placing things over it and a light wooden board as Base. This is required as load cell bends slightly when some weight is placed over it. Circuit Diagram: Interfacing HX711 Load Cell with Arduino Assemble the circuit as shown in the figure for designing “ Arduino Weighing Machine using Load Cell HX711 Module” or simply “ Interfacing HX711 Load Cell with Arduino“. Working Explanation: Before making the whole circuit to work it is necessary to “ calibrate load cell HX711 with Arduino“. For “calibrating Load Cell HX711 with Arduino” we need to put 100g weight at starting when the LCD displays put 100g weight. Once 100gm weight is kept over the load cell, calibration is done.
