R307 Optical Fingerprint Sensor
—The R307 is an optical fingerprint sensor that stores templates on the module itself and reports a match over serial, so no fingerprint data reaches the microcontroller.
Specifications
- Optical fingerprint scanner with ring indicator
- Stores up to about 1000 templates on-module
- Matching done on the sensor — returns an ID, not an image
- Serial (UART) interface
- 3.6-6V supply
- Enrolment and search under one second typically
What you can build with the R307 Optical Fingerprint Sensor
- Door and cabinet access control
- Attendance and time-clock systems
- Secured tool and equipment lockers
- Gun safe and cash box locks
Compatibility
Works with Arduino, ESP32 and Raspberry Pi over serial using the Adafruit Fingerprint library. Because matching happens on the module, the project never handles biometric images — worth stating if you are documenting a build for others.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
