If you’re a maker, hobbyist, or engineer looking to measure strain, the Arduino platform can help you do it with relative ease. By connecting a strain gauge to an Arduino board, you can measure the amount of strain or force applied to an object. This can be useful for a variety of applications, from monitoring stress levels in materials to tracking the movement of objects.
What is a Strain Gauge?
A strain gauge is a device that measures strain, or the amount of force applied to an object. It consists of a material that changes its electrical resistance when deformed. Strain gauges are usually made of thin metal foil and are attached to an object to measure the amount of strain it’s exposed to. The strain gauge is then connected to an amplifier, which amplifies the small changes in resistance to a detectable level.
Connecting a Strain Gauge to Arduino
The Arduino platform makes it easy to connect a strain gauge to an Arduino board. To do this, you’ll need a few parts, including an amplifier, a bridge, and a resistor. The amplifier amplifies the small changes in resistance from the strain gauge, the bridge balances the two sides of the strain gauge, and the resistor sets the sensitivity of the strain gauge.
Once you’ve assembled the components, you’ll need to write a program for the Arduino board that will read the strain gauge’s output and store it in a variable. You can then use this variable to determine the level of strain or force applied to the object.
Using the Data
Once the data is collected, you can use it to monitor the amount of strain on an object over time. This is useful for a variety of applications, from tracking the movement of objects to monitoring stress levels in materials. You can also use the data to control external devices, such as a motor or a valve, based on the strain readings.
Conclusion
Connecting a strain gauge to an Arduino board is a simple and straightforward process. With the right components and programming, you can measure the amount of strain or force applied to an object and use the data to monitor stress levels or control external devices. If you’re looking to measure strain, the Arduino platform is an excellent choice.
