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 →Ultrasonic Ranging Sensor URM37 URM37 Ultrasonic Ranging Sensor is a versatile distance sensor for robotics, tank level checks, obstacle detection, and automation projects.
It supports several output methods, making it easier to fit into many Arduino and Raspberry Pi style builds.
This part fits monitoring, measurement, logging, alarms, and automation builds. It works well in Arduino, ESP32, and Raspberry Pi style projects where you need reliable real-world data from the ultrasonic ranging sensor urm37.
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus sensor cables, headers, or a matching expansion shield for faster setup.
Useful add-ons include displays, data logging modules, waterproof enclosures, and matching Gravity cables or sensor shields.
