Split Single Phase Real Time Whole House Energy Meter for IoT, Arduino, ESP32, ESP8266 - Monitor Electricity Usage Remotely
MONITOR ELECTRICITY USAGE REMOTELY - Instantly see changes in energy uses with your phone
REDUCE YOUR ELECTRIC BILL - Real time sampling of 2 current channels & 1 voltage channel
ACCURATE - Calculates Active Power, Reactive Power, Apparent Power, Power Factor, Frequency, and Temp
EASY TO USE - Uses standard current transformer clamps to sample current - Works with any Arduino compatible MPU (ESP32, ESP8266)
SMALL - 40x50mm - Comes with circuit board only. Additional parts are needed (listed below)
The CircuitSetup ATM90E32 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.
The ATM90E32 IC from Microchip is versatile and affordable. We've put it on a 40x50mm PCB and connected all the useful bits, so it's easy to hook up to an ESP or Arduino board of choice, current transformers, and an AC transformer (for voltage & powering the board). Next, all you have to do is load the software on your MPU via the Arduino IDE to start seeing how much power your house is using!
Features:
Samples 2 current channels & 1 voltage channel (expandable to 2 voltage) Calculates Active Power, Reactive Power, Apparent Power, Power Factor, Frequency, and Temp Uses standard current transformer clamps to sample current Includes buck converter to power ESP8266, or ESP32 (one AC transformer is required, which is used to sample current) Can set warnings for over voltage & sag, over current, and frequency thresholds 2 IRQ interrupts, and 1 Warning output Energy pulse output (pulses also correspond to 4 LED's) SPI Interface Measurement Error: 0.1% ADC Resolution (bits): 16 Intended for single split phase homes
What you'll need: Current Transformers: SCT-013-000 (will have to cut off connectors and wire into the boards screw connectors) or Magnelab SCT-0750-100 (must sever burden resistor connection on the back of the board since they have a built in burden resistor) AC Transformer: 9v An ESP32 (ESP8266 or anything else that has an SPI interface) Jumper wires with Dupont connectors to connect the two boards. Software to load on your MPU using the Arduino IDE: EmonESP and ATM90E32_Arduino EmonCMS, ThingSpeak or similar
