New Product: CVSensor – USB to USB Current / Voltage Sensor – I2C INA219

Need to measure current and voltage  through a USB cord programmatically?  Gather lots of data dynamically?    Then you need a USB CVSensor.

You can buy it here at the SwitchDoc Store.

The USB CVSensor is an USB to USB current and voltage measuring device.  It uses an INA219 to accurately (and dynamically) measured currents and voltages through a USB plug.

Measure:

• Startup Currents and Voltages
• Track Dynamic power consumption in systems
• Gather data using Arduino or Raspberry Pi base systems.
• Use in Solar Power Systems
