DFRobot SEN0690 Linear Flexible Potentiometer Sensor
DFRobot SEN0690 Ultra-Thin Linear Flexible Potentiometer Sensor can transform curved surfaces into touch interfaces. This ultra-thin (0.45mm), flexible ribbon sensor serves as a compact alternative to bulky mechanical sliders, enabling linear touch control for wearables, curved dashboards, and soft robotics. Powered by graphene technology and IP67-rated for water and dust resistance, the DFRobot SEN0690 is engineered for diverse operational environments and offers immediate compatibility with standard development platforms like Arduino® and Espressif ESP32.
