ATOM Socket is a smart power socket designed to be used with the ATOM main control board. It is equipped with a built-in HLW8032 high-precision energy metering IC, which enables it to accurately measure various electrical parameters such as line voltage, current, active power, apparent power, and power factor. These parameters can be accessed through serial communication.

The socket is designed with an external jack that follows Japanese standard specifications, ensuring compatibility with commonly used plug types. Inside the socket, there is an integrated single-circuit relay capable of handling AC power in the range of 100-120V at a maximum current of 10A. This relay is responsible for controlling the power supply to the socket, allowing for easy and convenient power on and off control.

When the ATOM main control board is integrated with a WiFi module, the ATOM Socket can be easily connected to a network for remote control and energy metering. This means that users can remotely control the power status of the socket and also monitor energy consumption from anywhere with an internet connection.

Additionally, the ATOM Socket features an extra socket that integrates an HY2.0-4P interface. This interface allows for interaction with external equipment, such as relay signal input and key signal output. This provides flexibility and opens up possibilities for integrating the socket with other devices or systems, enhancing its functionality beyond basic power control.

    Nice replacement for third party AC power controllers

    My needs were quite simple , being able to toggle power on and off from a rasp pi python app. Using MQTT this was easily accomplished. I am not using the v/a monitoring at this time. Bought two more for future tasks.

    Great Device need more documentation/Arduino support

    a lot of hardware is not supported by arduino by default or libraries don't exists would love to see more community work. i love the hardware you sell but more support of the chipsets would be great.

    It is a good product, though I would not recommend it for beginners.

    It is a useful product to keep track of power consumption, although it is up to the user to create their own firmware. Be careful when creating the application, as the buttons may work unexpectedly due to GPIO39 issues.
