The fingerprint sensor is the combination of the R305 FP + PIC MCU card which can read different fingerprints and store in its own flash memory. The sensor can perform three functions, namely Add, Empty Database or Search Database and return the stored fingerprint ID.

Any of three functions can be called simply by making the sensor under the pin or pressing on board three switches. The answer is an error or it is indicated by the integrated LED. The response is also returned as a single serial data byte. The return byte is a valid ID or error code. The response byte is a single byte at 9600 bps making the whole sensor very easy to use. We have provided LED indicators and the function switch is now ready to use when you receive it. Just give the power and start using the sensor using on-board switches. You can then proceed to make the external application using these functions.

Characteristics

• Easy to use
• Status LED
• Function Switches
• Single-byte response
• Work at 5V
• UART 9600bps response
