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 →This is a standard LED Current Meter 10A. It measures 0-9.99A with 2% accuracy. Best suitable for current display in the circuit.Just apply four wires without any extra circuit or components, it gives the reading straight away. Easy to use, and good company with robot application.It has three color to select, green/blue/red.
Warnings: Please carefully follow the instructions for wiring. The power supply terminal and measurement terminal of this LED Current Meter are used common-ground connection. So,the measurement terminal of current meter must be cascaded after loads. It's better that power supply of the current meter is isolated.
