Unit AC Measure
SKU:U164
Description
Unit AC Measure is a single-phase AC measurement unit with isolation, using the STM32 + HLW8032 solution, capable of real-time monitoring of high-precision current, voltage, power, and other data. It is equipped with an AC isolation chip B0505ST16-W5 and communicates with the STM32 through the EL357 optocoupler isolation chip. Users can read the measured data via I2C communication. This product is suitable for power supply information collection, remote smart home appliances, and other fields.
Note
Input Voltage
Measurement input voltage working range: must be AC 100~240V@10A, otherwise the device cannot work properly.
