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 Water Turbidity Detection Kit is an environmental sensor with analog and digital output designed for light logging, optical switching, line tracking, and brightness-aware projects. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Operating Voltage: 5V DC; Analog Output: 0~4.5V; Sensor Interface: XH2.54.
| Product | Sensor style | Standout |
|---|---|---|
| Water Turbidity Detection Kit | environmental sensor with analog and digital output | Current item |
| Light Analog Log-Scale Sensor GA1A12S202 | light sensor with analog output | analog output |
| Gesture and RGB Sensor APDS 9960 | gesture sensor | digital output, infrared sensing |
| Turbidity Analog Sensor | 5V DC | environmental sensor with analog and digital output | analog output, digital output |
This sensor is a good fit for automatic brightness control, line followers, light meters, UV monitors, flame detection, and optical encoders.
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.

|---|---|
| Sensor Interface | XH2.54 |
| Output Mode | Analog Output : 0~4.5V Digital Output : High/low-level signal (threshold adjustable via potentiometer) |
| Analog Output | 0~4.5V |
| Digital Output | High/low-level signal (threshold adjustable via potentiometer) |
| Operating Voltage | 5V DC |
| Working Current | 40mA (Max) |
| Module Size | 38.6mm x 22.1mm |
