IBEM is a compact Solar System IoT Battery Energy Monitor, which can accurately measure up to +-200A peak DC, nominally +-100A continuous, complete with voltage and power monitoring.
Based on the new Espressif ESP32C3 Mini, which has both WiFi and BT, the SDK board is provided with a in-built bi-directional DC current sensor, via M8 bolt terminals, into a 16-bit ADS1115 four channel ADC.
Using the on-board 4.5 to 80V DC-DC SMPS, the board can easily be safely powered direct from the battery source – an also continually monitor the battery voltage.
Interface for programming, and development, is thought the standard Type C USB, into the on-board ESP32C3 DevKit port. So making development completely self-contained.
