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 Digital Push Button is a button or switch input module with digital output designed for sensing, logging, and automation. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Supply Voltage: 3.3V to 5V; Interface: Digital; Size: 22x30mm.
| Product | Sensor style | Standout |
|---|---|---|
| Digital Push Button | button or switch input module with digital output | Current item |
| Button Digital For Arduino and Raspberry Pi | button or switch input module with digital output | digital output |
| Vibration Switch - HDX2 | vibration sensor | waterproof build |
| Rotation Sensor Rotary Encoder Analog | rotation sensor with analog output | analog output |
This sensor is a good fit for general sensing, logging, and automation builds.
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus a breadboard and jumper wires for quick setup and testing.
Useful add-ons include breadboards, jumper wires, displays, enclosures, and logging modules, depending on how you plan to power, mount, and log the sensor.
