Summary of SPLIT HOME ENERGY METER FEATURES ESP32 WITH MICROCHIP ATM90E32
This article introduces the Split Single Phase Energy Meter, an affordable device for real-time home energy monitoring. It connects to ESP8266 or ESP32 modules to transmit data to platforms like EmonCMS and tracks solar generation. The meter features high accuracy (0.1% error) and measures active, reactive, and apparent power, frequency, and temperature using standard current transformer clamps. It includes built-in power regulation, multiple output interfaces, and compact dimensions.
Parts used in the Split Single Phase Energy Meter:
- ESP8266 or ESP32 microcontroller
- Microchip ATM90E32 chip
- Standard current transformer clamps
- Built-in buck converter
- EmonCMS software platform
- SPI Interface
- Zero crossing output
- Energy pulse output
Split Single Phase Energy Meter. Affordable remote energy monitoring for your entire home
The Split Single Phase Energy Meter can monitor the energy usage in your entire home in real time. It can easily be hooked up to an ESP8266 or ESP32 to wirelessly transmit energy usage data into a program like EmonCMS. It can also be used to monitor solar power generation to keep track of how much power you are making.
With The Split Single Phase Energy Meter You Can:
- Save Money!
- See exactly how much money is being spent on energy in real time
- Find appliances that are using too much electricity
- View & Gather Energy Data
- View the energy usage of your entire home
- Or track solar power generation
- Review and graph historical energy data
- View usage data in the EmonCMS Android or iOS apps
- Be Informed!
- Independent of your power company’s meter
- Set up alerts for over or under usage
- Not spend a ton on energy monitoring!
- Built to be inexpensive but very accurate
- Costs hundreds less than some other solutions
