Dr. Wattson Energy Monitoring Board V2

 What is Dr. Wattson? Dr. Wattson is an Energy Monitoring Module from Upbeat Labs that allows you to easily incorporate high quality AC energy monitoring & measurements in your next project! It is coupled with easy to use Arduino & Python libraries that make getting quality AC energy data – like RMS Current, RMS Voltage, Power Factor, Line Frequency, Active/Reactive/Apparent Power – a breeze, with just a couple of lines of code. The unit comes pre-calibrated, enabling you to start taking quality measurements from 90-240v, at either 50 or 60 Hz, and for currents up to 15A. You don't need any additional CT/VT or other components. Dr. Wattson is based on the MCP39F521, a single-phase power monitoring chip from Microchip. If you're familiar with the MCP39F521 you can also use Dr. Wattson as a breakout board for the MCP39F521 Measure Big. Or Small With a 4000:1 Dynamic Range and capable of 0.1% accuracy, the MCP39F521 is a versatile chip that allows great flexibility with measuremen
