[SUB][Arduino][Sensor] EC Sensor (SKUDFR0300)

The SKU DFR0300 electrical conductivity sensor is an Arduino module that allows you to monitor water quality by measuring the electrical conductivity in water. The sensor works by measuring the concentration of ions in the water, which is a simple way to determine the purity of the water. It uses the analog pins of an Arduino to read the voltage and convert it to electrical conductivity, and a calibration feature helps maintain accuracy over temperature and environmental changes.
