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 →The Atlas Scientific Conductivity K 10 Kit is a complete electrical conductivity (EC) measurement solution designed for accurate water quality testing and monitoring.
Built for high-conductivity liquids, this kit is ideal for saltwater testing, chemical process monitoring, and industrial water analysis. It provides the essential components needed to measure conductivity levels from 70 µS/cm to over 500,000 µS/cm.
The kit includes an EZO™ Conductivity Circuit, a K 10 conductivity probe, an electrically isolated carrier board, and calibration solutions. These components help users build reliable monitoring systems while reducing electrical interference.
With support for Arduino and Raspberry Pi, the Conductivity K 10 Kit is suitable for laboratory research, industrial applications, and automated water quality projects.
