App note: Watt-hour meter based on the STM32F101 microcontroller

ARM Microcontroller based watt-hour meter implementation from STMicroelectronics. Link here (PDF) This document describes, in detail, the hardware and software implementation of a watthour meter using the STM32F101 microcontroller. This cost effective watt-hour meter uses shunt with an operational amplifier as a current sensor, an embedded 12-bit ADC for current and voltage measurement, GPIO for […]
