  • Amplifier for load cells HX711

      Amplifier for load cells HX711
    The SparkFun 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 youll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control, or simple presence detection.The HX711 uses a two wire interface (Clock and Data) for communication. Any microcontrollers 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 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)The YLW pin acts as an optional input that is not hooked up to the strain gauge but is utilized to ground and shield against outside EMI (electromagnetic interference). Please keep in mind that some load cells might have slight variations in color coding.Features:Operation Voltage: 2.7V-5VOperation Current:

  • Combinator board for load cells

      Combinator board for load cells
    The SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard 4-wire wheatstone configuration. If you open up an electronic bathroom scale youll find a large rats nest of wires. The Load Sensor Combinator was created to combine the 12 wires found in a bathroom scale into the standard 4-wire wheatstone bridge configuration. You can either use four individual load sensors or simply purchase an off-the-shelf bathroom scale and hacking the combinator into it rather than trying to design a base to properly mount four load sensors. This board works great with our Load Cell Amplifier breakout board; the five pins on the edge of the combinator line up directly to the five pins on the amplifier. If your amplifier and supporting electronics are more than a few inches away from the scale an RJ45 footprint is provided. The four wheatstone pins (E+/E-/S+/S-) as well as the shield pin are connected to twisted pairs within a standard cheap Ethernet cable. This allows the amplifier board to be placed many feet away from the scale itself. The combinator board also includes a footprint for the DS18B20 one wire temperature sensor. This allows the user to gather the temperature of the scale in case there is a large variance between the scale and the amplifier. These three pins are accessed through the RJ45 connection as well allowing remote temperature readings to be gathered over one twisted pair Ethernet cable.

  • Force sensitive resistor - 600mm

      Force sensitive resistor - 600mm
    Force sensitive resistor from Interlink, FSR 408. The resistance changes depending on the amount of force applied to the resistor. When no force is applied, the resistance is approx. 10Mohm, and decreases as the force increases. The connections consists of pins with 2.54mm pitch. The back side is self-adhesive for easy mounting on most smooth surfaces. The resistor can be cut to desired length without affecting the resistance. - Measuring range: 100g - 10Kg - Length: 622.3mm - Width: 15.24mm - Sensor area: 609.22 x 5.08mm

  • Force sensitive resistor 0.3"

      Force sensitive resistor 0.3"
    This is a force sensitive resistor with a round, 0.5" diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MOhm. This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR. These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale. * Overall length: 1.75" * Overall width: 0.75" * Sensing diameter: 0.3"

  • Load cell 200Kg round - TAS606

      Load cell 200Kg round - TAS606
    This disc load cell (sometimes called a strain gauge) can translate up to a whopping 200kg 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 disc. With this gauge you will be able to tell just how heavy an object is, if an objects 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. Disc load cells are a bit easier to mount than bar-style load cells, making them more straightforward to implement into a design. Each load cell is made from an steel-alloy and is capable of reading a capacity of 200kg. 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. Dimensions: 20mm x 11mm, 2000mm Wire

  • Sparkfun OpenScale

      Sparkfun OpenScale
    The SparkFun OpenScale is a simple-to-use, open source solution for measuring weight and temperature. It has the ability to read multiple types of load cells and offers a simple-to-use serial menu to configure calibration value, sample rate, time stamp and units of precision. 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. The SparkFun OpenScale will enable you to turn a load cell or four load sensors in a Wheatstone bridge configuration into the DIY weigh scale for your application. The OpenScale was designed for projects and applications where the load was static (like the beehive in front of SparkFun HQ) or where constant readings are needed without user intervention (for example, on a conveyor belt system). A load cell with an equipped OpenScale can remain in place for months without needing user interaction! 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 OpenLog, an FT231 with mini USB, for USB to serial connection; the HX711, a 24-bit ADC for weigh scales; and the TMP102, for recording the ambient temperature of your system. The OpenScale communicates at a TTL level of 9,600bps 8-N-1 by default and possesses a baud rate configurable from 1,200bps to 1,000,000bps.
