About Expandable-6-Channel-ESP32-Energy-Meter
CircuitSetup Expandable 6 Channel ESP32 Energy Meter The CircuitSetup Expandable 6 Channel ESP32 Energy Meter is a real time power and energy monitor built around two ATM90E32AS metering ICs. The main board measures six current transformer channels and one voltage reference by default, and you can stack up to six add on boards for a total of 42 current channels. It is a good fit for whole home monitoring, subpanels, solar, large branch circuits, and multi voltage or 3 phase projects. The first AC AC adapter powers the main board and provides the primary voltage reference. A second voltage can be measured on the…
