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 Analog Voltage Divider V2 Gravity is a sensor module with analog output designed for maker projects, data logging, and responsive electronics. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Input voltage (DC): Maximum 25V, Minimum 0.0245V; Interface: Analog; Size: 22x30mm (0.87x 1.18 in).
| Product | Sensor style | Standout |
|---|---|---|
| Analog Voltage Divider V2 Gravity | sensor module with analog output | Current item |
| Rotation Sensor Rotary Encoder Analog | rotation sensor with analog output | analog output |
| Rain Steam Water Sensor Gravity | rain sensor with analog output | analog output, humidity sensing |
| Sound Sensor Analog | sound 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.
