Description

Raspberry Pi Current Measure and Record Probe

This project consist of LEM isolated current sensors. By the help of sensors current is converted to analog signal. MCP3204 12 bit ADC converts analog signal to digital. Raspberry Pi Zero reads current value and records to database or Excel file.

Additionally zero crossing detector gives pulse at zero point of voltage.

By the help of the BNC connectors analog signal of the current can be seen on the osciloscope. BNC to BNC cable can attach measure probe and osciloscope. Signal can be tracked on scope at the same time.
