R301T Capacitive Fingerprint Reader Access Control Module Sensor Scanner USB UART RS232 TTL 15KV

Overview 1 R301T capacitive fingerprint module adopts imported capacitor small surface acquisition chip integrated fingerprint algorithm chip with fingerprint input image processing feature extraction template generation template storage fingerprint comparison 1 1 or fingerprint search 1 N and other functions suitable for fingerprint locks fingerprint safes fingerprint access control and other occasions 2 In battery powered applications the touch sensing power supply is DC3 3V 5V and the current is about 5uA It must be always powered When there is a finger it senses a low level wakes up the MCU and powers up the fingerprint module thus saving power the goal of 3 R301T can be used together with K200 K212 K215 K216 fingerprint control board Specifications Supply voltage DC 4 2 6 0VWorking current 40mA typical Peak current 50mAFingerprint image entry time 0 3 secondsAcquisition window area 10 10 mmImage pixel 192 192 pixelImage resolution 508dpiBoard size 33 4 20 4 board thickness 1 0mmMatching method Comparison method 1 1 Search method 1 N Template file 496 bytesStorage capacity 1700 piecesSecurity level five levels low to high 1 2 3 4 5 Rejection rate FRR 1 0 Search time 0 3 seconds 1 1000 hours mean Host computer interface RS232 TTL logic level 3 3V USBCommunication baud rate 9600╳N bps where N 1 12 default value N 6 ie 57600bps working environment Temperature 20C 45C Relative humidity 10 RH 85 RH
