the fingerprint sensors are available in both capacitive and optical varieties. both of them are based on the same technology, but the capacitive one has a much larger sensing area, while the optical one is much smaller and uses a camera instead. the r307 and r308 chips used by these sensors are spi compatible. this means that they are connected to the spi port of the arduino. the data is sent from the sensor to the processor (arduino) using a clock line, while the chip is not driving the clock line. this is called synchronous operation. the clock line is used to activate the chip, while the data lines are used to send and receive the data.

the rest of this tutorial will guide you through the process of getting a grow sensor into your arduino project. the sensor comes with a few documentation, in pdf format. the download button is on the bottom of the page.
in this tutorial, we will use the r307 model to demonstrate how to use the library for interfacing the module to an arduino board. the serial communications protocol used in this module isusb-serial. it is a standard usb protocol that we can use in any usb-enabled computer such as windows, linux, and mac os.
as stated earlier, the r307 has six instructions. the first four instructions, read, write, write mirror, read mirrorare used to read the fingerprints. write and write mirror instructions are used to store the fingerprint information to the template stored in the internal flash memory. and read and read mirror instructions are used to download the templates from the flash memory. the r307 also has two other instructions:resetandgetserialnumber. the reset instruction is used to clear the fingerprints in the sensor buffer, and the getserialnumber instruction is used to get the serial number of the scanner, which is a unique identifier of the scanner. this unique identifier is used to identify the scanner over the network when we transfer the templates. in addition, the r307 has another set of instructions calledjumpwhich is used to make the module jump to a certain point in the firmware.
