Description

AC Measure Unit is a single-phase AC measurement module with isolation capabilities. It utilizes the STM32+HLW8032 scheme to monitor high-precision current, voltage, power, and other data in real time. The module features a built-in AC isolation chip, B0505ST16-W5, and communicates with the STM32 through the EL357 optocoupler isolation chip. Users can access the measured data via I2C communication. This product is suitable for applications in power supply information collection, remote smart home appliances, and other related fields.
