Overview
This is a photoelectric water liquid level sensor that operates using optical principles.
The advantages of this photoelectric water liquid level sensor are good sensitivity and no need for mechanical parts - meaning less calibration!
The corrosion resistant probe is easily mounted and can handle high temperature and high pressure.
The arduino liquid sensor is equipped with an interface adapter for compatibility with the DFRobot "Gravity" interface.To ease the difficulty of using this arduino liquid sensor, a Gravity Interface is adapted to allow plug&play.
The Arduino IO expansion shield is the best match for this sensor connecting to Arduino, as this liquid sensor is able to work at 3.3V which makes it compatible with Raspberry Pi, intel edison, joule and curie.
Note: Avoid placing the sensor near bright lights or in direct sunlight as these can cause interference.

If you are a pet owner, you know how important it is to keep furry companions fed and happy – even when life gets busy! With the Arduino Plug and Make Kit, you can now build a customizable smart pet feeder that dispenses food on schedule and can be controlled remotely. It's the perfect blend of functionality and creativity, designed to simplify your life and delight your cat, dog, rabbit, hamster, or cute creature of choice. Here’s everything you need to automate feeding your pet This intermediate project is packed with advanced features, made easy by the intuitive Plug and Make Kit. With its modular components, creating your own smart pet feeder is straightforward, fun, and easy to customize. Here’s what you’ll need: Arduino Plug and Make Kit, which already includes UNO R4 WiFi, Modulino Distance, Modulino Buttons, Modulino Pixels, and Qwiic cables A continuous servo motor (such as this one, for example) Some jumper wires and screws for assembly A 3D printer (to create the case either with the files we provide, or with your own designs!) Simply follow our step-by-step tutorial on Project Hub to put everything together, customize your code, and print the 3D encasings. Once the setup is complete, you can remotely control the feeder via a ready-to-use Arduino Cloud dashboard, where you’ll set dispensing schedules, adjust portion sizes, and even customize LED lights to match your pet’s mood. The Modulino Distance sensor ensures food comes out only when needed, while the Modulino Buzzer adds some audio feedback for a playful touch. Make it the cat’s meow! As you know, the Plug and Make Kit’s versatility allows for endless possibilities. Feel free to expand this pet feeder project with additional features! For example, you can add a motion-activated camera to capture your pet’s activities, or a real-time weight monitor to track how much food is consumed. You can even activate voice commands for an
