This device measure the electrical conductivity of an aqueous solution. The included probe is a K=1 model. Calibration is somewhat complicated - see the DFRobot wiki for instructions on calibration. Functions are provided to supply the appropriate values. By default, the values used in the DFRobot arduino example are used.", "Aliases": ["dfrec"], "Categories": ["ec", "conductivity"], "Connections": ["analog", "uart"], "Project Type": ["industrial"], "Manufacturers": ["dfrobot"], "Kits": [], "Examples": { "Java": ["DFREC_Example.java"], "Python": ["dfrec.py"], "Node.js": ["dfrec.js"], "C++": ["dfrec.cxx"], "C": ["dfrec.c"] }, "Specifications": { "Operating Voltage": {"unit": "V", "Typ": 5}, "Measurement Range": {"unit": "mS/cm", "low": 1, "high": 20}, "Operating Temperature": {"unit": "degC", "low": 5, "high": 40} }, "Urls" : { "Product Pages": ["https://www.dfrobot.com/product-1123.html"], "Datasheets": [""], "Schematics": ["http://image.dfrobot.com/image/data/DFR0300/DFR0300_v1.0_schematic.pdf"] } } } }
