Quickly build an electrical conductivity meter, plug and play!

Overview

DFRobot Gravity: analog electrical conductivity meter V2 is specially used to measure the electrical conductivity of an aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection, and other fields. You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series. 

This ec meter product, as an upgraded version of the electrical conductivity meter V1, greatly improves the user experience and data precision. It supports 3~5v wide voltage input, and is compatible with 5V and 3.3V main control board; The output signal filtered by hardware has low jitters; The excitation source adopts AC signal, which effectively reduces the polarization effect, improves the precision, and prolongs the life of the probe; The software library uses two-point calibration method, and can automatically identify standard buffer solution, so simple and convenient.

With this product, the main control board (such as Arduino), and the software library, you can quickly build an electrical conductivity meter, plug, and play, no welding. DFRobot provides a variety of water quality sensor products, uniform size, and interface, not only meet the needs of various water quality testing but also suitable for the DIY of multi-parameter water quality tester.

Conductivity is the reciprocal of the resistance, which is related to the ability of the material to carry the current. In the liquid, the reciprocal of the resistance, the conductivity, is the measure of its ability to conduct electricity. Conductivity is an important parameter of water quality. It can reflect the extent of electrolytes present in water.

Tips:
In order to ensure measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature and achieve automatic temperature compensation.

Features:

  • 3.0~5.0V wide voltage input
  • Hardware filtered output signal, low jitter
  • AC excitation source, effectively reduce polarization
  • Gravity connector and BNC connector, plug and play, no welding
  • Software library supports two-point calibration and automatically identifies standard buffer solution, integrates temperature compensation algorithm
  • Uniform size and connector, convenient for the design of mechanical structures

Applications:

  • Water quality monitoring.
  • Aquaculture.
  • Hydroponic & Aquaponic

Project Tutorial by fmuller999

This code sets up an Arduino device to connect to WiFi and communicate with the OpenAI API. It uses the Adafruit_SSD1306 library to control a small OLED display, displaying messages and responses from the API. The device sends a prompt to the API asking "What is Arduino?" and waits for a response, which it then displays on the OLED screen. This is done using a secure SSL connection, and the API key is stored as a variable in the code. Overall, this code demonstrates how an Arduino device can be used to interact with web services and display data on a small screen.

This YouTuber recreated the D-O droid from Star Wars: Episode 9 with Arduino
This YouTuber recreated the D-O droid from Star Wars: Episode 9 with Arduino
November 21, 2019

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!
