This S-Type load cell can translate up to 100kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response and proportion to the strain (e.g., pressure or force) applied to the form. 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.

Each straight bar load cell is made from alloy steel and is capable of reading a capacity of up to 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 and feature two M4 and two M5 sized through-holes for mounting purposes.

It has Four lead wires which can be connected to  HX711 A/D Pressure Sensor.  It is easy to use with driving voltage 5-10V and produces the output voltage as per the force changes over it.

FSR series is a force sensing resistor that exhibits the unique characteristic of dynamic resistance related to the amount of applied force. Typical force-sensing resistors are characterized for HumanMachine Interface (HMI) or Machine-Machine Interface (MMI) applications with a sensing range from circa 20g to 5Kg. Specific device characteristics will depend on the size, shape, and materials used in construction. Force-sensing resistors are intended for applications where a delta in applied force is to be detected. They are not intended for high accuracy or specific weight measurement applications.

Note: Images shown may vary from actual product in terms of branding and labeling.

The ADP800 sensor family is Aosong’s series of digital differential pressure sensors designed for high-volume applications. The sensors measure the pressure of air and non-aggressive gases with superb accuracy and no offset drift. The sensors cover a pressure range of up to ±500 Pa (±2 inch H2O / ±5 bar) and deliver outstanding accuracy, also at the bottom end of the measuring range. The ADP800 Series features a digital 2-wire I2C interface, which makes it easy to connect directly to a microprocessor. The outstanding performance of these sensors is based on Aosong’s patented sensor technology. The differential pressure is
measured by a thermal sensor element using flow-through technology. The well-proven technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.

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 you’ll 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.

Onboard 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 weighing 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.

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!

Features:

1. Selectable 10SPS or 80SPS Output Data Rate
2. Local & External Temperature Sensors
3. Fixed & Adjustable Gain

Package Includes:

1 x SparkFun OpenScale
