This is a DFRobot Gravity: Photoelectric High Accuracy Liquid Level Sensor. It is operates using traditional optical principles. The advantages of this are a high sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperatures and high pressures. The sensor is equipped with an interface adapter for compatibility with the DFRobot "Gravity" interface. The Gravity: Photoelectric High Accuracy Liquid Level 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 senor 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.


Features:

  1. Equipped with an interface adapter for compatibility with the DFRobot "Gravity" interface
  2. High sensitivity
  3. Less calibration
  4. No need for mechanical parts

 


Packages Includes:

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
