Description The M5Stack ATOM Socket Kit is a smart power socket kit compatible with the ATOM controller. It combines an ATOM Lite controller with an ATOM Socket base for remote power control and energy metering projects. The official product page describes the socket as using the HLW8032 high-precision energy metering IC, allowing electrical parameters such as line voltage, current, active power, apparent power and power factor to be read through serial communication. The socket uses a Japanese/American standard outlet and an integrated single-channel relay for power on/off control. Paired with the ATOM controller's Wi-Fi capability, it can be used for network-connected smart socket and smart appliance control applications. Features Smart power socket kit: combines ATOM Lite with an ATOM Socket base. HLW8032 energy metering: supports voltage and current detection, power calculation and power factor readings. Single-channel relay: controls power on/off for AC 100 to 120V @ 10A or DC 28V @ 10A loads. Serial communication: official UART baud rate is 4800bps with 8E1 format. Measurement performance: official dynamic range is 1000:1, active power error 0.2%, effective current error 0.5% and effective voltage error 0.5%. JP/US socket standard: Japanese/American standard socket listed with PSE standard. External control interface: HY2.0-4P interface for relay signal input and button signal output. Wi-Fi-ready control: can connect to a network when paired with the ATOM controller.
