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 Float Switch Plastic Water Level Control is a liquid level sensor designed for obstacle detection, touchless triggers, object counting, and simple automation. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Work temperature range: -10 ~ 80 °C.; Work voltage: 110V.
| Product | Sensor style | Standout |
|---|---|---|
| Float Switch Plastic Water Level Control | liquid level sensor | Current item |
| Float Switch Plastic Water Level Control Right Angle | liquid level sensor | pressure sensing |
| Non-Contact Liquid Level Switch | button or switch input module | general-purpose sensing |
| Reed Switch Module | magnetic sensor with digital output | general-purpose sensing |
This sensor is a good fit for robot obstacle avoidance, touchless dispensers, automatic doors, object counters, parking aids, and level 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.
