Product Description

         Get the high-quality Force pressure sensor 0.5-inch diameter at a low price. 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 been apply to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.
