IBEM-ESP32C3-SDK U.FL Version 3D (New April 2024)

IBEM Overview

IBEM is a compact, self-contained, Solar System IoT Battery Energy Monitor, which can accurately measure current flow nominally up to +-100A (+-200A Peak), and voltage up to 80V DC.  This board essentially providing a complete voltage and power monitoring solution for your 48V, 36V, 24V or 12V batteries.

Based on the new Espressif ESP32C3 Mini, which has both Wi-Fi and BT, the IBEM SDK board is provided with onboard bi-directional DC current sensor, via M8 bolt terminals, into a 16-bit ADS1115 four channel ADC. No external shunts required.

Using the onboard 4.5 to 80V DC-DC SMPS, the board can easily be safely powered directly from the battery source -- This also providing continuous monitoring of the battery voltage.

Interface for programming, and development, is thought a standard Type C USB, into the onboard UART and ESP32C3, so making development and use, completely self-contained.

Using the provided I2C interface, an OLED display can be plugged directly into the board, if required, for local monitoring and status information.

Opensource IBEM Firmware is provided on our GitHub, using the standard PlatformIO platform. This monitors Current, Voltage (and Temperature), to derive Power Energy information, which can then be sent to your Home Automation, or cloud service, via provided MQTT or Domoticz, as standard.
