Here is a new finger print security system project which uses R303/R305 module. A previous finger print security system project published on this site uses SM630. its available here. R305 module is almost half the price of SM630. So we are giving a new security system project with R303/R305 module. The AT89S52 microcontroller is used in this project to control the R305 fingerprint module. The features of R305 is given below. Power DC 4.5V-6.0V Interface UART(TTL logical level)/ USB 1.1 Working current Typical: 100mA Peak: 150mA Matching Mode 1:1 and 1:N Image acquiring time <0.5s Storage capacity 256 Security level 5 (1, 2, 3, 4, 5(highest)) Even though it can store 256 fingers, in this project we are using only 100 fingerprints. |
