Due to the importance of RFIDs we propose today a simple, stand-alone project, which is basically a simple transponder enabled lock. This lock is equipped with a relay to be used to control an electric gate opener or a simple lamp. We’ll use a great module, very practical because it incorporates everything you need to make a transponder reader: the ID-12 by Innovations Technology. This component integrates the exciter coil, the logic to control absorption and that for code identification.

This project comes in  kit . Some components have to be soldered to the included PCB.

• Up to 127 tags can be stored.
• Possibility to store\delete a single tag and reset the memory.
• Organization Dynamic memory: each tag is stored in the next available location.
• Monostable output operation (activation for 1 second) or bistable.
• Buzzer indicator
• Power supply 11 to 15 Vdc - 150 mA
• Dimensions 84 mm x 50 mm
