Measure AC power consumption without cutting wires using this highly accurate, non-invasive Qwiic current sensor.

Designed to work with a non-invasive current clamp, the SparkFun Qwiic ADE7953 Non-Invasive Current Sensor makes it easy to monitor the power drawn by AC devices over I2C without disconnecting the circuit or cutting or splicing any wires. By simply wrapping a clamp around your live wire and plugging it in, you can safely measure energy consumption and integrate the data directly into your microcontroller projects.

Precise Current Metering:

The ADE7953 at the heart of this Qwiic Current Sensor is a single-phase multifunction metering IC that can also measure neutral current on a second channel. It's highly accurate with less than 0.1% error in measuring both active and reactive energy over a dynamic range of 3000:1. It also provides an instantaneous IRMS measurement with less than 0.2% error. The ADE7953 communicates over I2C (Default), SPI, and UART. These interfaces are hardware selectable by adjusting solder jumpers on the board.

Hardware Connections and Breakouts

To make using this sensor as straightforward as possible, this board provides several physical connection points for your monitoring hardware:
Audio Jack Input: A 3.5mm jack connects to the ADE7953's Current Channel A, allowing users to easily connect a non-invasive current clamp (not included) to the board.
Solderless Data: Dual Qwiic connectors provide a simple, daisy-chainable I2C connection to your main system.
Current Channel Access: The board also breaks out both the A and B current channels to plated-through-hole pins but does not break out the ADE7953's voltage measurement channel, so this board can only measure AC current.
While an external current clamp with a 3.5mm plug is required to use this sensor, we wanted to offer this board on its own in case you want to use your own clamp or pick up a Split-Core Current Transformer. Alternatively, we also carry these two parts in a single Non-Invasive Current Sensor Kit!
The breakout has a 0.1"-spaced plated through-hole (PTH) header that breaks out the ADE7953's power and communication pins. It also routes to the ADE7953's interrupt pin and the Channel A zero-crossing pin. The Interrupt pin is a user-configurable active VALUE signal to indicate events such as. The zero-crossing pin outputs a pulse each time the current waveform crosses zero to determine line frequency and synchronize measurements to the AC cycle.
