However, while we are used to address the topic of conductivity in the field of electronics, things get a little bit more complicated when we try to apply the concepts to chemical solutions such as salty water. The RobotGeek Tilt Sensor is a fast and flexible way to add an Arduino tilt senor Project. DFRobot Gravity: analog electrical conductivity meter V2 is specially used to measure the electrical conductivity of aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection and other fields. Today I want to introduce a project of designing a solar tracker using two servo motors, a light sensor consisting of four LDRs and Arduino UNO board. 4v, so the probes for high-conductivity environments are usually made of resistant materials such as platinum, titanium, gold-plated nickel or graphite, making them somewhat expensive.
