Signal Name

Signal Description


Touch Power 3.3V

Touch   sense function need to supply power separately. Power: DC3.3V±0.1V, Current:   1.5uA to 2.5uA


Finger Detect

Output high level   when detected finger, and output low level once finger left



Module transmit   output, 3.3V TTL logic



Module receive   input, 3.3V TTL logic






DC input, range of   Voltage is 3.3V ± 10%


FP Reset

Reset at low level   (reset time>100ms), Work at high level. After Reset, it will cost about   350-400ms for system initializing and programs loading; Only after that the   module can communicate with MCU by UART.

FAQs About CAMA-SM15 Optical Fingerprint Sensor Module

1. Does the SM15 optical fingerprint sensor module support Windows, Android or Linux system?
    Answer:  Yes, SM15 optical fingerprint sensor module can work with these operating system.  Actually SM15 optical fingerprint module is an OEM optical fingerprint module, it can work with any operating system based on our command protocol.

2. Does the SM15 optical fingerprint sensor module support read and write fingerprint template ?
    Answer:  Yes, SM15 optical fingerprint module support read and wrtie fingerprint template . If you need, you can use Read Template Command to extract the fingerprint templates from SM15 module and use Write Template Command to write the fingerprint templates into SM15 module from other place. 

3. Does the SM15 optical fingerprint sensor module's template data compatible with other manufacturer's fingerprint template data?
    Answer: No.  SM15 optical fingerprint sensor module only support CAMABIO fingerprint template format only, it does not compatible with other manufacturer's fingerprint template format.  

4. What should we do if we need more than 3,000 fingerprint users ?
    Answer:  We suggest you to build a server system by our CAMA-2000 Desktop USB fingerprint scanner and store the fingerprint templates on the server.  And the terminal device with SM15 only for capture fingerprint  and transfer the fingerprint template to server to do verification and then return the result to terminal device.
