## Description

The Gravity Analog 20A Current Sensor measures both AC and DC current using the Hall effect, outputting a proportional analog voltage to your microcontroller. With high-voltage isolation built into the circuit design and a non-conductive acrylic base plate, it's designed for safe use in automation and power monitoring applications. The standard Gravity 3-pin interface allows plug-and-play connection to Arduino and other compatible boards via the included analog sensor cable. Key Features AC & DC Measurement – 0 to ±20 A DC or 0 to 17 A RMS AC Hall Effect Sensing – Non-contact current measurement High-Voltage Isolation – Safe measurement up to 220V AC / 311V DC Analog Output – Proportional voltage output via Gravity 3-pin connector Safety Features – Non-conductive acrylic base plate to prevent short circuits ±3% Accuracy – Suitable for monitoring and automation applications Compact – 39 × 22 × 17 mm, 18 g Specifications Power Supply – 5.0V DC Current Range – 0 to ±20 A AC Current Range – 0 to 17 A (RMS) Max Voltage Endurance – 220V AC / 311V DC Relative Error – ±3% Interface – Gravity PH2.0-3P Dimensions – 39 × 22 × 17 mm Weight – 18 g Warning: This sensor can measure high-voltage circuits. Exercise caution when working with mains voltage. Ensure proper isolation and follow all electrical safety procedures. Ideal For Power monitoring and energy management Automation and control systems Battery charge/discharge monitoring Arduino-based current measurement projects Package Contents 1× Gravity Analog 20A Current Sensor 1× Gravity Analog Sensor Cable Resources Product Wiki
