Description
Description Unit AC Measure is an isolated single-phase AC measurement unit based on an STM32 + HLW8032 solution, capable of real-time high-accuracy monitoring of current, voltage and power data. It integrates the AC isolation converter B0505ST16-W5 and communicates with the STM32 via the EL357 optocoupler. Users can obtain measurement data through the I2C interface. This product is ideal for power information collection, remote smart appliances and similar applications. Input Voltage Operating measurement range: must be AC 100 ~ 240V@10A, otherwise the device will not work properly.
