Description

Take current monitoring to the cloud and stay connected from anywhere in the world using Particle Electron*.

Monitor DC currents anywhere cellular service is available using the Particle cloud infrastructure. This DC Current Monitoring controller consists of ADS7828 12-Bit Analog-to-Digital Converter connected to eight ACS712-05 hall-effect current sensors.

This controller uses I2C communications and includes a convenient I2C output connector for easy expansion. On-Board address jumpers allow device start address selection for up to four current monitoring controllers on a single I2C port.

No software development is required as our GitHub repository has a complete driver for monitoring 8-Channels at 5 Amps.

Physical implementation is easy, simply pass current through each pair of screw terminals and read the voltages on the ADS7828. The ADS7828 will return approximately 2.5V when 0 current is passed through the ACS712. Forward current will cause the ADS7828 to return values between 2.5 and 5VDC as current increases. Negative current will cause the ADS7828 to return values from 2.5 to 0 as current increases. In theory, this design could monitor AC, but our software currently supports DC only at this time.
