This is a all in one solution for finger print detection - industrial grade sensor, controller with relay output & remote for configuration. Direclty control loads like lights, fans, door locks, access control systesm using the onboard relay based on registered fingerprint scans.

This is an all in one finger print scanner kit with sensor, controller and remote. It includes an industrial grade sensor to detect and recognise finger prints. The controller can store fingerprints and turn on a relay when a stored fingerprint is detected. A remote can be used to program the various settings on the controller like - relay on time, store new fingerprint, delete existing fingerprint in database, etc.

R503 is an industrial grade fingerprint sensor in stainless stell housing - it is dust and water proof. It comes with panel mounting and can be eaily mounted.  It uses an optical image recognition sensor and high performance DSP microcontroller to detect and recognise fingerprint. It also comes with a round multicolored illumination for status indication. This sensor reads fingerprint when placed on the face of the sensor and stores fingerprints on in its internal databases. These fingerprints can be easily retrieved from the database and compared against new scans.

The K216 Controller communicates with the R503 and controls a relay based on the fingerprinter being scanned. The controller turns on the relay only for valid fingerprints that are previously stored. Users can control a load such as 240V AC Operated Lights, Fans, Door Locks, motors, etc using the relay based on the authorised fingerprints.

A 12 Key IR Remote can be used to program specific settings on the controller like - relay on time, add/remove authorised fingerprints, etc. This makes the controller configurable without the need for coding/programming. 

Overall an excellent plug and play solution for Access Control, Home Automation, Electric Locks etc. 

K216 + R503 Finger print Sensor Kit. IR Remote is used to store fingerprints and a Light is operated using the relay output when a store fingerprint is scanned


  •  This all-in-one optical fingerprint sensor will make adding fingerprint detection and verification simple and convenient
  • The relay output can also be interfaced with a microcontroller like Arduino, Raspberry Pi, NodeMCU, etc
  • The sensor has an LED ring built around the detection pad, which can be set to red, blue, or purple for a great user experience.
  • These modules are typically used in electric safes - there's a high-powered DSP chip that does the image rendering, calculation, feature-finding, and searching.
  • Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash, and search. You can also enroll new fingers directly - up to 300 fingerprints can be stored in the onboard FLASH memory.
