Description
Gravity: Capacitive Fingerprint Sensor (I2C, 80 fingerprints) - ideal for education & makerspaces
With the Gravity Capacitive Fingerprint Sensor, you can bring biometrics to life in the classroom: Students can implement real identity verification - from the first fingerprint enrollment to securely unlocking a project via I2C with Arduino, micro:bit & Co.
Why it is suitable for schools, STEM & clubs
Quick start with embedded security: Add, search for, and delete fingerprints - directly using the appropriate Arduino library and example code.
Robust & student-friendly: Compact design, CNC-machined metal ring, and LED ring for visible feedback (ideal for learning about UX/UI).
Plug-and-play in the classroom: Gravity connector system, operates at 3.3-5 V, communication via I2C.
Technical highlights (brief)
Stores up to 80 fingerprints
360° capture & matching + self-learning for more reliable recognition
Verification time approx. 300-400 ms, 508 dpi, sensor area 8 × 8 mm
Typical classroom and project ideas
“Smart Locker”: Locker/material cabinet accessible only to registered users
“Access Control” for the makerspace tool board: Unlock devices/prototypes
Ethics & data protection in computer science: Discuss the opportunities/risks of biometric methods (including policy design)
Scope of delivery
Sensor, adapter, cable (including Gravity-4P)
