ATOM Socket Kit (HLW8023) - CN



ATOM Socket CN is a smart power socket adapted to ATOM main control. Built-in HLW8032 high-precision energy metering IC, through the serial port communication can read the electrical parameters (line voltage, current, active power, apparent power and power factor) of the socket. The external jack adopts Chinese standard specifications, and the internal integrated single-circuit relay (AC-220V@10A) is used to control the power on and off of the socket. With the ATOM main control integrated with WiFi module, the power socket can be easily connected to the network for remote control And electric energy metering. The extra socket integrates HY2.0-4P interface, which can interact with external devices (relay signal input, key signal output).
