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 →Small submersible DC water pump, runs on 2.5-6V. Magnetic drive, low current draw, moves up to about 120 L/H. For fountains, aquariums, hydroponics, and DIY watering.
Drop it in water, connect a tube to the outlet, power it. Available in vertical, horizontal, and amphibious styles, with plain-lead or USB versions.
| Voltage | 2.5-6V DC |
| Current | 130-220mA |
| Flow rate | 80-120 L/H |
| Max lift | 40-110mm |
| Drive | Magnetic, brushless |
| Outlet | 7.5mm OD / 5mm ID |
| Working life | 500 hours continuous |
Keep it fully submerged. Running dry overheats and damages the motor.
