Bend Detection Sensor RAKwireless RAK12016 (Spectrasymbol FS-L-0095-103-ST)

RAKwireless RAK12016 is a WisBlock flex/bend sensing module when you want mechanical deflection to become a digital signal inside an embedded or IoT system. The sensing element, Spectrasymbol FS-L-0095-103-ST, is a flexible strip whose resistance changes as it bends, making it suitable for capturing bend angle, deflection, or motion on curved or moving parts.

A key practical advantage is that the module includes an ADC converter, so the bend signal can be read digitally over I2C. That simplifies integration for WisBlock and other microcontroller projects: you avoid analog input constraints, external ADC hardware, and much of the analog wiring complexity.

With a stated bending range of 1 to 180 degrees and 1-degree accuracy, the module is commonly used in:

Human-machine interfaces (HMI) and wearables, such as finger/hand motion capture for input devices, gesture prototypes, or training/recovery concepts.

Soft robotics and mechanical prototyping, measuring bend state on flexible components.

Industrial monitoring, where deflection indicates mechanical stress or movement on guards, brackets, covers, or fixtures.

Safety and trigger logic on production equipment, using “bending under load” as an event signal for alarms or shutdown behavior.

The module runs on 3.3 V and comes in a compact 15 × 25 mm format for quick prototyping and embedded integration.
