gauge based load cells Usually with larger, non-push button bar load cells you will want to hook up the. For more information, check out the resources below: Need some inspiration for your next project? These pins are labeled with colors; RED, BLK, WHT, GRN, and YLW. Simply attach a four-wire or five-wire load cell of any capacity, plug the OpenScale into a USB port, open a terminal window at 9,600bps, and youll immediately see mass readings. Output (O Signal (S) or Amplifier (A) is white O-, S-, or A- is green or blue Some load cells might have slight variations in color coding such as blue instead of green or yellow instead of black or white if there are only four. Any microcontrollers gpio pins should work and numerous libraries have been written making it easy to read data from the HX711.
The breakout board is compatible with any wheat-stone bridge based load cell which should allow a user to measure everything from a few grams. The SparkFun Load Cell Amplifier is a small breakout board for the HX 711 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 youll be able to get.

The four wires coming out from the wheatstone bridge on the load cell are usually: Excitation (E) or VCC is red Excitation- (E-) or ground is black. Any gpio pin will work for either. For smaller, push-button or disc load cells, you will want to make sure to screw in the disc to a bottom plate (or surface you are measuring force against and center the beam, plate, or whatever else you are wishing to measure the force. Therefore, the center tap to the strain gauge is the white/green wire. How to Solder: Through-Hole Soldering, this tutorial covers everything you need to know about through-hole soldering. On board the SparkFun OpenScale is the ATmega328P microcontroller, for addressing your communications needs and transferring your data to a serial terminal or to a data logger such as the. Fritzing diagram of HX711 amplifier connected to a RedBoard Now, if you would like to set up four single load sensors with our combinator board and amplifier, connect the five pins labeled RED, BLK, WHT, GRN, YLW on the combinator to the matching pins. Your calibration factor may be very positive or very negative. Related manuals, do hookup in Medicine Hat you need a help?
Page 1 of 10 Load Cell Amplifier HX 711 Breakout Hookup Guide Getting Started The HX 711 load cell amplifier is used to get measurable data out from a load cell and strain gauge.
This Hookup Guide will show you how to get started with this amplifier using some of the various load cells.
HX 711 on breakout board - This microchip is specially made for amplifying the signals from load cells and reporting them to another mircocontroller.
The load cells plug into this board, and this board tells the Arduino what the load cells measure.
5kg load cell - Load cells are specially shaped.
