سنسور اثر انگشت finger print R301

توضیحات

این ماژول اثر انگشت توانایی ذخیره سازی 1700 اثر انگشت را دارد و  می توان از طریق ارتباط سریال UART با این ماژول ارتباط برقرار کرد، به این صورت که یا آن را به طور مستقیم به میکروکنترلر متصل کرد و یا اینکه توسط رابط MAX232 و یا مبدل USB به سریال به کامپیوتر متصل نمود.

Description:
