This force - sensitive resistor (FSR) features a round sensing area with a 0.5 - inch diameter. It changes its resistance based on the pressure applied to the sensing area. The more pressure you apply, the lower the resistance. When there's no pressure, its resistance exceeds 1MΩ. It can detect forces ranging from 100g to 10kg. Two pins with a 0.1 - inch pitch extend from the sensor's bottom, making it breadboard - friendly. There's a peel - and - stick rubber backing on the opposite side of the sensing area for easy mounting. These sensors are easy to set up and great for basic pressure sensing, though not extremely accurate. Use them to detect squeezing, but avoid using them as a scale. Dimensions include an overall length of 2.375 inches, an overall width of 0.75 inches, and a sensing diameter of 0.5 inches. It comes with useful documents like an FSR Integration Guide, QuickStart Guide, Hookup Guide, and Bildr Tutorial.
Using this force - sensitive resistor is easy. First, you can use the peel - and - stick rubber backing to mount the FSR on the surface you want. Then, connect the two pins on the bottom of the sensor to your breadboard, thanks to their 0.1 - inch pitch. To sense pressure, just apply force to the round sensing area. Keep in mind that this sensor isn't highly accurate, so it's best used to detect if something is being squeezed rather than as a precise scale. When it comes to maintenance, keep it in a dry place and avoid exposing it to extreme temperatures or excessive moisture. Also, don't apply forces outside the 100g - 10kg range as it may damage the sensor. If you need more detailed information, refer to the FSR Integration Guide, QuickStart Guide, Hookup Guide, and Bildr Tutorial that come with the product.
