Elecbee ACS712 30A Current Sensor Module Hall Effect Bi-directional Current Detection Board 30A Range 5V Analog Output for Arduino

The Elecbee ACS712 30A Current Sensor Module is the professional solution for engineers needing to monitor heavy-duty electrical loads without risking damage to sensitive microcontrollers. By solving the challenge of bi-directional current sensing in high-power applications, this module allows for real-time tracking of motor stalls, battery charging cycles, and power surges. Its Hall Effect design ensures that your control circuit remains electrically isolated from the load, significantly increasing overall system safety and longevity.

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

• Sensor Chip: ACS712ELC-30A Hall Effect Linear Sensor
• Measurement Range: Optimized for -30A to +30A DC or AC
• Analog Sensitivity: Precise 66mV per Ampere output
• Operating Voltage: Standard 5V DC via onboard pins
• Module Dimensions: Compact 32mm x 14mm double-sided PCB

Built on a high-conductivity FR4 PCB, the module features reinforced traces to handle 30A loads with minimal thermal dissipation. The analog-to-voltage conversion is highly compatible with 5V systems like Arduino and 3.3V systems like ESP32 (with external voltage dividers). Note: To maintain maximum signal integrity, avoid mounting this module near transformers or high-power magnets, as external magnetic interference can affect the Hall sensing accuracy. This module is the ideal choice for vibration-resistant current monitoring in renewable energy and smart-home applications.
