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 Time of Flight Distance Sensor VL53L0X ~30 to 1000mm is an infrared distance sensor designed for distance measurement, obstacle detection, level checks, and basic automation. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Operating Voltage: 3.3VDC-5VDC; Data I²C Voltage: 3.3VDC; Infrared Wavelength: 940nm.
| Product | Sensor style | Standout |
|---|---|---|
| Time of Flight Distance Sensor VL53L0X ~30 to 1000mm | infrared distance sensor | Current item |
| VL53L4CD Time-of-Flight Distance Sensor Carrier with Voltage Regulator, 120cm Max | infrared distance sensor | motion sensing |
| VL53L1X Time-of-Flight Distance Sensor Carrier with Voltage Regulator, 400cm Max | infrared distance sensor | motion sensing |
| Adafruit VL6180X Time of Flight Distance Ranging Sensor | light sensor | ultrasonic ranging |
This sensor is a good fit for robot obstacle avoidance, tank level checks, parking aids, object counters, and range alarms.
Pair it with an Arduino-compatible board, ESP32, or Raspberry Pi, plus a breadboard or 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.

Check the pin labels on the Time of Flight Distance Sensor VL53L0X ~30 to 1000mm and match them to your controller voltage, ground, and signal pins. Keep wiring short and verify the logic level before powering the module. Infrared and optical readings change with target color, surface finish, distance, and strong ambient light. Test with your real target before final mounting.
