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.

Connect Arduino to a web browser over Bluetooth and see a 3D model and graph moving around - magic!
While it’s yet to make its premiere, Matt Denton has already built the D-O droid from Star Wars: The Rise of Skywalker using a MKR WiFi 1010 for control, along with a MKR IMU Shield and a MKR Motor Carrier. The droid scoots around on what appears to be one large wheel, which conceals the Arduino boards as well as other electronics, batteries, and mechanical components. Denton’s wheel design is a bit more complicated mechanically than it first appears, as its split into a center section, with thin drive wheels on the side that enable differential steering. On top, a cone-shaped head provides sounds and movement, giving the little RC D-O a ton of personality. The droid isn’t quite finished as of the video below, but given how well it works there, the end product should be amazing!
