Based on a high-performance Cortex processor, combined with a high-security commercial fingerprinting algorithm, the UART Fingerprint Sensor (D) features functionalities such as fingerprint enrolling, image acquisition, feature finding, template generating & storing, fingerprint matching and more! Without any knowledge about the complicated fingerprinting algorithm, all you need to do is send some simple UART commands to quickly integrate it into fingerprint verification applications which require small size and high precision. Features * Easy to use by some simple commands * Commercial fingerprinting algorithm, supports functions like fingerprint enrolling, fingerprint matching, fingerprint image acquisition, fingerprint feature uploading * Capacitive sensitive detection, just touch the collecting window lightly for fast verification * Highly integrated hardware, processor and sensor in one small chip, suitable for compact applications * Narrow stainless steel rim, supports 360° omni-directional verification * Embedded human sensor, the processor will enter sleep automatically and wake up when touched for lower power consumption * Onboard UART connector, easy to connect with hardware platforms such as Raspberry Pi Specifications Sensor Capacitive touch sensor Resolution 508 DPI Image pixels 160×160 Image greyscale 8 Sensor dimension R15.5 mm Fingerprint capacity 150 Matching time <500ms (1:N, and N≤100) False acceptance rate < 0.001% False rejection rate < 0.1% Operating voltage 2.7~3.3V Operating current < 50mA Sleep current < 16uA ESD Contact discharge 8KV / aerial discharge 15KV Communication port UART Baudrate 19200 bps Operating environment Temperature: -20°C~70°C Humidity: 40%RH~85%RH (no condensation) Storage environment Temperature: -40°C~85°C Humidity: <85%RH (no condensation) Pinout Package Contents * 1x UART Fingerprint Sensor (D) * 1x 6-pin squid wire Resources * Product Wiki * User manual https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2023-03-07 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2023-12-27 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2024-09-18 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2024-11-29 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2024-11-30 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2025-08-06 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2025-11-28 https://elecena.pl/product/22726217/round-all-in-one-capacitive-fingerprint-sensor-d 2025-11-29
