Elecbee ACS712 20A Current Sensor Module Hall Effect Bi-directional Current Detection Board 5V Analog Output for Arduino

The Elecbee ACS712 20A Current Sensor Module is the professional solution for engineers needing to monitor high-amperage loads without risking damage to sensitive microcontrollers. By solving the challenge of bi-directional current sensing, this module allows for real-time tracking of both charging and discharging cycles in battery systems or motor stalls. Its Hall Effect design ensures that your control circuit remains electrically isolated from the load, significantly increasing system safety and longevity.

This industrial-grade detection board is engineered for linearity and precision. The technical specifications include:

• Sensor Chip: ACS712ELC-20A Hall Effect Linear Sensor
• Measurement Range: -20A to +20A DC or AC
• Analog Sensitivity: 100mV per Ampere output
• Operating Voltage: 5V DC via onboard pins
• Module Dimensions: 32mm x 14mm compact PCB

Built on a durable double-sided FR4 PCB, the module features high-conductivity traces to handle 20A loads with minimal heat generation. The analog-to-voltage conversion is compatible with 5V systems like Arduino and 3.3V systems like ESP32 (with appropriate scaling). Note: To maintain maximum signal integrity, avoid mounting this module near transformers or high-power magnets, as external magnetic fields can affect the Hall sensing accuracy. This module is the ideal choice for vibration-resistant current monitoring in renewable energy and smart-home applications.
