DFRobot Gravity Analog AC Current Sensor (20A) - Non-Contact Open-Type Transformer Probe
The DFRobot Gravity Analog AC Current Sensor (20A) is a non-contact current monitoring module designed for safe, in-line measurement of AC loads up to 20A. It outputs an analog voltage signal compatible with 3.3V or 5V microcontrollers like Arduino, Raspberry Pi, and ESP32, making it ideal for energy monitoring and equipment protection applications.
Features
- Non-contact AC current measurement up to 20A RMS for enhanced electrical safety.
- Open-type transformer probe clamps onto wire without cutting or splicing.
- Analog output (0-3V or 0-5V) compatible with 3.3V/5V microcontroller ADCs.
- Gravity 3-pin interface for plug-and-play connectivity with DFRobot shields.
- Wide operating voltage range from 3.3V to 5.5V DC.

The DFRobot Gravity AC Current Sensor utilizes a split-core current transformer (CT) principle for non-invasive AC current measurement. The open-type probe clamps around a single conductor, inducing a voltage proportional to the AC current flow, which is then conditioned by the signal conversion module into a safe, readable analog output.
This module is engineered for integration into energy monitoring systems, equipment protection circuits, and smart home automation. It provides a safe, isolated measurement solution compatible with common development platforms, eliminating the risks associated with direct series connection or high-voltage handling.
