current-sensing

Open-source industrial IoT platform: modular STM32 sensors, firmware, hardware, and cloud telemetry.

Battery Management System (BMS) for a 3S 12V 80Wh lithium-ion battery pack, focused on safe and intelligent fast charging, thermal protection, and cell health tracking. (2023)

An isolated half-bridge motor driver board featuring 6N137 galvanic protection, an IR2101 bootstrap topology, and precise AD8418 bidirectional current sensing.

Work-in-progress USB-C current measurement schematic with STM32F042, MAX4239 amplifiers and STEMMA QT I2C; legacy KiCad sources and PDF.

Arduino program for the ZES ZSOM-M01 and ZSOM-M01-CS01 board that detects abnormal current patterns with configurable thresholds, featuring a Python GUI for visualization and logging.

Arduino Nano ESP32 pool cover controller with current-based obstacle detection — a working replacement for a failed Latham/Coverstar 1601 (E0301 / LPE0301RC) board on a two-way electric motor

Heating plant instrumented like a BMS plant room on ESPHome (WIP): boiler flow/return, pressure, current and states; opto-isolated boiler call, hot-water timer and cylinder stat signals alongside Evohome relay states; cylinder temperatures, pressures and tundish discharge; UFH plant.

An ATmega328P-based smart grid fault detector featuring high-side current sensing via INA180A1 and voltage monitoring. It includes hardware fault latching with a CD4013 flip-flop, robust P-MOSFET load switching, 12V-to-5V power regulation, and TVS/Schottky transient protection for reliable power grid diagnostics.
