Fingerprint sign-in, access control system.Fingerprint lock devices: door locks, safes, steering wheel locks, padlocks, gun locks, etc.Small size, low power consumption,10uA for standby mode.Powerful self-learning function: the more you use, the more accurate the recognition.Built-in 2KByte storage: support up to 100 fingerprints.Large size, high power consumption, and relatively low accuracy, can't identify the living body, low security Strong abrasion resistance, good environmental adaptability, and good stability Poor abrasion resistance, easily susceptible to sweat, stains, finger wear, etc. Grove - Capacitive Fingerprint Scanner / SensorĬan identify biological characteristics, only identify living body, high safety, small size, low power consumption, high accuracy So what's the difference? Well, let's show you the merits and demerits of both sensors so that you can choose the best one to meet your needs. We have already released the Grove optical fingerprint sensor, this time we bring you the Grove - Capacitive Fingerprint Scanner / Sensor. And with the help of the Grove UART connector and the Arduino library we offered, you can build your own Arduino fingerprint sensor/scanner easily.
Defeat hardware fingerprint software driver#
We add the power level shift circuit on the Grove Driver board so that this module can work with both 3.3V and 5V systems. After each successful fingerprint recognition, the latest challenge feature values can be integrated into the fingerprint database to continuously improve the fingerprint features, making the experience better.
The system is equipped with a high-performance fingerprint algorithm, and the self-learning function is remarkable. In addition, it is worth mentioning that there is a lovely RGB light around this module to indicate whether the fingerprint recognition is successful. This module features many advantages such as small size, small fingerprint template, low power consumption, high reliability, fast fingerprint recognition, etc.
The Grove - Capacitive Fingerprint Scanner / Sensor is based on the KCT203 Semiconductor fingerprint recognition module, including a high-performance MCU, a vertical RF push-type fingerprint sensor, and a touch sensing device. Edit Grove - Capacitive Fingerprint Scanner/Sensor
