Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →EDUP Wifi Adapter is a USB wireless signal receiver, which is built using Ethernet cable. It adopted USB2.0 gold-plated transmission interface, having a wide application range such as be applied to Ipad, desktop, laptop and other devices which support all Windows operation system (Windows XP/ 7/ 8/ 8.1/ 10/ raspberry pi). In addition, it equips with a 6dBi high gain antennas, which can take apart and rotate freely on the side up to 90 degree. It is convenient that it can achieve install quickly without drive but just you make sure install the software first. The data rates have up to 150Mbps and it can receive the wifi signal form 360 degree. I believe that it just what you need.
